100% Completion

> *"You know, some people feel like they haven't 'beaten' the game until they found every single available token. But I think that's just unnecessary padding."*
>
> **Ultimate Deadpool**, *Spider-Man: Shattered Dimensions*

Way of extending potentially short gameplay almost but not quite infinitely by setting completed tasks (such as collecting a certain number of items and doing optional sidequests) as a percentage, sometimes given explicitly. This feeds into the obsessive nature of the player.

Gamer opinion regarding this mechanic is roughly divided between those who feel that the goal should be easy for all players to obtain and those who believe it must be difficult enough for only a few players to reach it during the game's lifetime. It is always Serious Business, however.

One does not usually need 100% to beat the game, but often will be rewarded with things like proper endings, infinite ammo, or "the making of" videos. Other times, you receive nothing but the satisfaction of putting so much time into completing everything in the game. This can get tedious however, especially if the game has several Empty Room Psychs or Missing Secrets. Or some spiffy new outfits. Or a very weird picture congratulating you.

Occasionally, this is humorously extended way past 100%. See also 100% Heroism Rating. Often related to Gotta Catch Them All. For the items a game requires you to collect to achieve this, see Pickup Hierarchy.

The trope has become more popular with the rise of Achievements and Trophies, allowing the player to not only get one hundred percent completion, but show everyone online that they did.

Have fun finding the Last Lousy Point.

**As an Ending Trope, Spoilers ahead may be unmarked. Beware.**

Examples of 100% Completion include:

## Internet Series

* Jirard Khalil, a.k.a. "The Completionist," does 100% completions on video games, and does humorously informative videos about them on YouTube, completing games like *Catherine* and *Super Meat Boy*. ( http://www.youtube.com/user/ThatOneVideoGamer )

## Video Games

* An online game called *Achievement Unlocked* parodies this. There are achievements for things like *pressing the space bar* and *dying*. And the reward? What reward? The game was meant as a *criticism* of achievement mechanisms in games (the game's designer made a previous game with a very unsubtle crticism of upgrade mechanisms), yet it became popular exactly because people loved the achievements so much. The sequel made the "satire" tone a lot lighter.
* To reach the final battle with Specter in the *Ape Escape* series, the player is *required* to obtain 100% completion (by capturing all the monkeys). However, monkeys aren't the only collectible in *Ape Escape*. You can reach the final battle without any Specter Coins, for example.
	+ Not to mention the gold medal you have to get for every level's time trial.
* The *Animal Crossing* games have an in-game catalog of all the items you've obtained in the game, allowing you to buy most of them easily. Collecting all the items of a type puts a star on the catalog for that group- collecting every item is about the closest thing these games have to a main goal.
	+ Not to mention the museum, or the town models.
	+ Or what about having your freaking house paid off, completely. Having your town weed free for a month, or having your house given a perfect score for style? Most of these things give you furniture in the end, but for some people accomplishing them is its own reward.
* *Ace Combat Zero* had this by way of getting all Ace Records, buying all weapons and aircraft, and beating the game on Ace difficulty with S ranks in each mission. Doing so makes Ustian flags appear in the hangar.
* *Airforce Delta Strike*: Get all the endings and unlock all the bonus planes.
* The *Armored Core* series of games usually have hidden parts for your Humongous Mecha in some stages along with getting graded for beating the stage. There's also a combat arena in most games which also net you parts. Then and some games even count your mission complete/fail ratio. So getting 100% can take some time and true 100% means you can't screw up once. Getting 100% usually gets you more parts. But the Armored Core series has a lot of Mission Pack Sequel games between next instalments so it means something in the end. Armored Core for Answer takes the cake by getting 100% nets you an emblem. Then again it's Nineballs emblem the game series memetic That One Boss. Also in universe some of the characters have 100% mission success rates, but that doesn't mean anything.
* *Assassin's Creed 2* has both the Monteriggioni value and the Synchronization stat; the former represents collectibles and progress. Scoring all the collectibles (all armors, weapons, paintings, feathers, etc.), clearing the story (to get the last assassination target portrait), and maxing out all the renovations to the town will result in the "Podesta of Monteriggioni" Achievement/Trophy (at 80% completion), a regular income of 15,000 florins every 20 minutes and a maximum of 60,000 florins that you can store. Synchronization on the other hand represents overall completion—which in addition to the above, and "synchronizing" with every Viewpoint, seems to require that you clear *every* possible mission, which may include the DLC ones.
* The reward for Hundred Percent Completion in *Backyard Skateboarding* is...a board.
* In *Banjo-Kazooie*, collecting 100 Jiggies will extend the ending, where Mumbo shows you three secrets and talks about Banjo-Tooie.
	+ In Banjo-Tooie, collecting 90 Jiggies unlocks the Character Parade in Replay Mode.
		- Banjo-Kazooie: Nuts & Bolts gives you an achievement and a gamerpic if you get all the Jiggies.
* *Baroque* (a strange sort of rougelike) has the item list which you fill up by giving/sending newfound items to the collector, you can save less then 15 items per tower run and the game has well over 200 items, and it's all random which ones you find in a given run, and even then, you still need to send up your badass gear since you need them to actually finish the tower. But wait, there's more! There's also Idea Sephira, which have a rare drop chance, in addition to counting as items, you can give it to the Baroquemongerer in order for him to add a line of fluff out of around 8 to whichever creature you dropped it from's "profile". Then of course, there are all the storyline videos, one of which there are three variations depending on how your first run ends, (clearing four levels of the dungeon, dying in the dungeon, or getting killed by pissing off an NPC outside the dungeon), and others depending on whether or not you flipped a heat switch regulating whether or not certain levels of the tower are frozen over or not. If that wasn't enough, there's the Baroques, Achievments for doing different actions in game, like clearing a certain point in the story, obtaining a certain number of items, not killing any enemy on a single tower run, includng stepping on the small bugs which can be hard to notice and harder to avoid, or doing absolutely nothing before you die outside the tower, (which means One Hundred Percent Completion can be impossible for some due to a bug which causes the controller to move slightly), granted, you gain boosts to your stats from gaining theese achievments, but there are loads and loads of them... Now, if you thought, "Okay, that's it, atleast there can't be anything else.." then you're dead wrong, lastly, you have voices, yes, you can collect in the Database, (where everything is stored), certain select voice tracks by hearing them, some of these require quite alot of work to reach, and quite a few of them are missable, there are over 150 of them. Needles to say, it's impossible to manage everything in one playthrough, but everything carries over into a New Game+.
* The *Baten Kaitos* games love to torture completionists. *Eternal Wings* had *about 1,000 magnus* that have to be collected for 100% completion. As if that wasn't daunting enough, there are a lot that can easily be Lost Forever; the Trail of Souls is the most infamous offender, but Maskless Mizuti is another nasty one.
	+ *Origins*, meanwhile, has the torturous Pac-Man sidequest, which involves feeding Pac-Man 147 different quest magnus. In addition, there's also the 'Milly's Rocks' sidequest, which involves pushing humanoid rocks around Nekkar. Thankfully, the game eased up on the Lost Forever; only three quest magnus and four field guide entries are missable.
* *Batman: Arkham Asylum* has things such as the various puzzles and challenges that the Riddler has scattered throughout Arkham for Batman to find. Listening to him gradually succumb to his inferiority complex as you find more and more of them is really quite fun.
	+ *Batman: Arkham City* is even more infuriating that Arkham Asylum when it comes 100% completion — assuming they have the 4 DLC packs, the player needs to complete the main storyline and all side missions **twice**, complete all 440 Riddler story mode challanges (riddles, trophies, etc.) and aquire all 888 Riddler's Revenge medals.
* In *Bayonetta*, the achievements/trophies are actually a part of the game in the form of "Umbran tears of blood". Getting the 51 achievements *and* catching the 51 crows hidden throughout the game (both requiring to beat the hardest difficulty setting) will give you the Climax Bracelet, a Game Breaker item. And if you are really hardcore, you can collect 10 million halos to fight a Nintendo Hard Bonus Boss − for which the aformentionned Climax Bracelet will actually be useful − who will reward you with a secret weapon. Which you can use in the Bonus Level of Hell Angel Slayer, to unlock a new character named Little King Zero. And if you *still* don't have enough, try and get platinum awards in every chapter on Normal to unlock Jeanne as a playable character. Pfiou!
* *The Binding of Isaac* has a golden god achievement which is gotten after getting all the items in the game during playthroughs.
* *Blast Corps* is incredibly persistent. Clear the main levels, find all the scientists, save a shuttle, clean up the moon, find all the bonus levels, get gold on all the bonus levels, find everything on the main levels, get gold on all the secret planet levels, get gold on all the time trials for the main levels, and your reward for all this is unlocking **platinum** targets for all the levels. The reward for getting all platinums is a very appropriate rank.
* The Achievements for *Blue Dragon* require you to, among other things, find every single item, every single monster, and max out every single character and character class. It's only for fun though, and the game's pretty much over after you beat the final boss (not counting New Game+).
* As part of its anvil Aesop, *Braid* 'rewards' players that achieve this by making the already sobering Gainax Ending even *worse*.
	+ *Braid* really has two levels of "100% completion," one of which is so secret that there aren't even any achievements for it. You do have to have 100% completion of the first five worlds (in terms of the 60-ish puzzle pieces, not of the various secret stars) to open the sixth, though.
* *Burnout Paradise* goes as far as 102%. Let's break it down:
	+ You get 100% (Burnout Elite) for winning all 120 events. Not that hard, just tedious. Your reward for that is gold paint on the "original" set of seventy cars.
	+ You get 101% (Criterion Elite) for doing all of the above, and also for breaking every time and crash record of every road, smashing all gates, jumps, and jumps, and getting all fifty Paradise Awards in the game. The jumps aren't that hard to find (there are only fifty), but getting all 120 billboards require some leaps of faith across parking lots, *very* accurate jumping, and, in one sadistic case, *very* quick breaking. And then there are the gates. There are 400 of them, and you can bet you'll get stuck on 394, trying to find the remaining six everywhere for days. Doing that nets you five carbon fibre cars (one for smashes, jumps, billboards, time rules, and crash rules) and platinum paint for the rest. For the extra percent, you have to do two complete sets of online challenges, with fifty in a set.
	+ The same counts for bikes; 100% for all 38 events, chrome finish for breaking the time rules for both day and night for every road, and the extra percent for completing two sets of online bike challenges (five in a set).
	+ And, for the truly masochistic, 102% for doing all *five hundred* challenges, getting 101% on the bikes and mainland, and 100% for Big Surf Island. Good luck.
		- The 102% finish is definitely a Luck-Based Mission since online players can be quite unreliable and difficult to rally into doing challenges. People can just sit on the map doing nothing, get lost trying to get to destinations, or just be a pain in the butt and attack other players trying to stick to the objective. Before an update to the game, if a player left during a challenge the whole thing would just end, adding another layer of frustration.
* *Call of Duty: Modern Warfare 2* played this straight, displaying the completion percentage in each of its mode: Singleplayer, Spec-Ops, and Multiplayer.
	+ Interestingly, after entering Prestige Mode in the multiplayer, the counter will go up past 100. A player level 25 in 3rd Prestige, for example, may have their percent counter at 454%. The ULTIMATE completion (that is, 10th Prestige) will display 1100%.
* *Castlevania: Symphony of the Night* allows you to explore 100% of the map. This score can then be increased to 200.6% in a "mirror" version of the castle; if you exploit a couple of wall bugs, you can increase this to ~240%!
	+ Most every item in Symphony of the Night is a random drop from enemies. Though these items don't count toward a noted in-game percentage, completionists who want to collect them all will be tortured by the low appearance rates, which result in revisiting the same room upward of one hundred times to get a single item. Further, certain items such as the Muramasa Blade and Familiars can be even be "leveled up," and the maximum level is only achievable by killing literally hundreds of thousands of enemies. Extreme collectors can gather 99 of every item in the game if they don't have anything else to do for the next few years.
* *Castlevania: Portrait of Ruin* takes this to an even greater extreme, with percentage markings for map completion separate for each map, as well as a combined total (1000.00%). In addition, there are percentages for items found/obtained, enemies fought (which are written in gray letters unless the player battles the enemies enough times to obtain the items they drop), and subweapons/skills obtained.
* In both *Castlevania Aria of Sorrow* and its sequel, *Dawn of Sorrow*, Soma not only has 100% map completion to look forward to, but 100% soul collection as well. Every non-human enemy in the game, save for their respective final bosses, has a soul that will randomly drop when Soma kills it, giving him a new power to play around with. Obtaining the soul of every enemy in the game will give him access to the infinite-MP Chaos Ring. Needless to say, this is extraordinarily difficult, with some souls refusing to drop until you slaughter the enemy 100 times or more.
* *Command & Conquer 3* has optional completion on every level for both completing bonus objectives, which are entirely bragging rights, and for collecting all the fun facts about the game world.
* Several *Crash Bandicoot* games have taken it all the way up to 120% and above, starting with *Crash Bandicoot 3: Warped* which offered 105% completion for clearing the two hidden levels, collecting all the bonuses on them, getting at least a golden relic on every single level's time trial, and finally collecting the hidden gem in the main warp room.
	+ *Crash Bash* features up to 200%, but good luck getting there.
* *De Blob* is a HUGE PAIN to get 100%; not only is there a time limit, but each level takes more than 15 minutes to complete and when you finish it, the level saves your scores and resets, meaning if you go back to it it's completely unfinished and you have to do EVERYTHING over again.
* *Destroy All Humans!* has a completion percentage. In the first game, 100% completion is nearly impossible, because it requires searching for probes scattered around the landscape, which don't show up on your radar. In the second game, completion is possible, but what happens when you finally reach 100% completion? Absolutely nothing.
* *Donkey Kong Country* took it up to 101%, giving you a slightly different ending for completion. Later games in the series kept upping the ante to things like *105%* (which requires a cheat code that removed most of the DK Barrels and all the midlevel star barrels).
	+ *Donkey Kong King of Swing* took it even higher with 200%. To get it, you must collect all 24 medals and 20 Crystal Coconuts, collect all the medals again in Diddy Mode, beat all the top times as both Donkey Kong and Diddy Kong in Time Attack Mode, and place first on all of the Jungle Jam events (including three that are only unlocked through a password screen accessible only through a code).
	+ *Donkey Kong Country Returns* also has 200% as its maximum amount. However, the only things that count towards completion percentage are the Kong letters (since you need them all to open all the stages) and completing said stages and then completing them again in Mirror Mode. Puzzle pieces and Time Attack medals don't factor in.
* *Doom* had several goals to shoot for per level: a time target, monsters killed, and secrets found. On Nightmare difficulty, however, monsters would respawn, making it possible to get more than 100% monsters killed, and at least one 'DOOM construction kit' actually advocates creating a 'secret area' that the player can't reach, to keep them coming back to look for 'that last 10 percent'.
	+ This is actually carried forward—minus the respawns—from id's previous game, *Wolfenstein 3D*.
* *Dragon Age: Origins* has the "Easily Sidetracked" achievement for completing 75% of all side-quests (no ordinary feat, considering it's a BioWare game) and the "Traveler" achievement for visiting *every* location in the game. The stage of the Final Battle counts as one.
* A gamer finished up Dragon Quest IX with a 100% completion rate. Amount of hours played? 773 HOURS.
* The fifth ending of *Drakengard* requires that you collect every weapon in the game first, which is completely arbitrary as what weapon you have equipped doesn't even matter to the plot of this ending. And the ending itself is rather anticlimactic.
	+ Nie R (which takes place in the future of the fifth ending) uses the same formula for getting all the endings, but the weapons are infinitely easier to get. Unlike Drakengard however the endings are more climactic and all Tearjerkers.
* *Final Fantasy X-2* is the only game in the series that scores players based on how much of the game they've completed, and it's notoriously sadistic about it—miss a single obscure, time-sensitive quest, pick the wrong option in an arbitrary choice, neglect to sleep at the Trauma Inn at least once a chapter *even though it serves no gameplay purpose*, or even *skip a cutscene*, and you lose any hope of 100% completion. Fortunately, your completion percentage will carry over to a New Game+.
	+ *Final Fantasy VII* had the Master materia; collect and master one of every kind of materia of a particular type, and you would be rewarded with a single materia that gives you all of the capabilities of all the rest of them combined, giving you more options in combat than you could possibly have otherwise. The optional bosses might count, though they generally don't give you any items that you couldn't get somewhere else.
	+ Getting the highest clan rank in *Final Fantasy XII* requires you not only to kill every mark, but also to complete the Sky Pirate's Den, the game's proto-achievement list. Among the achievements are things like encountering every monster in the game (including all the rare monsters), triggering every Quickening finisher at least once and having visited every section of every game area (thankfully excepting the ones you can't return to.)
	+ Rewards for completing side quests are becoming more popular in Final Fantasy; *Crisis Core: Final Fantasy VII* featured 300 extra missions that needed to be done for full completion of the game, not to mention many a Guide Dang It side quest. The reward is a literally God-level Zack, though. New entry to the series *Dissidia Final Fantasy* features an achievement system with some very obvious goals such as completing each character's story line and number of battles fought, along with some obscure ones such as distance traveled across the game's maps and how high you can raise your luck level, to make 150 "missions" in all.
	+ *Final Fantasy XIII*, being on the Play Station 3 and 360, supports Trophies/Achievements, which provides a percentage figure to work towards. To get all of the trophies, you will have to (among other things) earn a five-star rating on all 64 Marks, and acquire every weapon and accessory in the game (not all at the same time, but you have to have had at least one of every unique item at some point). Given the game's Upgrade system, this means not only acquiring all of the basic weapons and accessories, but also leveling them up.
	+ With *Final Fantasy IX'*s Tetra Master, getting perfection in the form of a perfect Collector's Rank of 1700 is insane. To do this, you have to collect all 100 card types (and you can only have 100 cards total at a time). On top of that, you have to "level up" your cards by using them enough so that they all have an attack type of A, and *have a different pattern of attack arrows on each one*. Your reward for doing this, however, is very disappointing. "Would you like to discard?" is superimposed over the other text in the card menu. Yes, that's right, for all your hard work, you get a glitch.
	+ One bit of 100% Completion in Final Fantasy IV: The After Years devolves into What the Hell, Player? territory. To complete the bestiary, you have to kill Shiva, Ramuh, Asura, Leviathan, and Bahamut instead of rescuing them from the Big Bad's control. You're a heartless bastard if you're proud to kill Rydia's family, AGAIN, just to fill a few blank entries.
	+ The Xbox 360 version of *Final Fantasy XI* has achievements for getting jobs to level 75. Since there are 16 jobs in the game, and getting *one* to level 75 takes at least *a month* of dedicated playing, getting 100% achievements will take a very, *very* long time.
	+ *Final Fantasy XIII-2* has 160 Fragments to collect, which nets an achievement. It also unlocks the cruelest Secret Ending in history, featuring the villain mocking the *player* for trying to find a way to defeat him.
* *Fire Emblem* had the Support Conversations page, which while you were working towards 100% completion, would reveal backstory of the characters whose supports you unlocked. The problem with this is that in order to fill the page to 100%, you'd have to play the game several times over, because each character could only have five support conversations in one playthrough. Not only that, but occasionally you'd be forced to pick a sub-optimal support to complete the page, thereby denying you the stat bonuses you could use. And in some games with this feature, there would be occasions where you could only pick one character and be forced to lose your chance at recruiting another.
* The first *Galaxy Angel* had, along with a set of CGs for every available girl, a secret set for Shiva, which accompanied The Reveal of the true identity of the White Moon's heir. Of course, getting them all made the next game make a lot more sense, as Shiva's secret was common knowledge in the game by *Moonlit Lovers*.
* Achievements in Xbox 360 games can be completely ridiculous. For example, 100% Completion of the Achievement list for *Gears of War* required you to get 10,000 kills in ranked matches to get the "Seriously..." achievement. The sequel increases the number to 100,000 but makes it much much easier by letting you get your kills in campaign mode.
	+ *Gears of War 3* takes this to absurd levels. "Seriously 3.0" requires the player to reach level 100 and get *every* gameplay medal at its maximum score. Note that some medals require achievements on certain difficulties that Xbox Live public matches don't support. For example, the "I'm a Beast!" medal requires the player to succeed on all 12 waves of Beast Mode on Insane difficulty—but only Private matches can have their difficulty set to anything other than "Normal."
		- On top of this, the player must also get 1000 kills with all six starting weapons, 500 kills with every other weapon (VS matches *only.* Campaign and Horde do *not* count), win 100 matches of Capture the Leader as the Leader *without ever getting captured once*, complete every non-PVP gametype on the highest possible difficulty, and more-or-less master every game type. Oh, they must also play as a female character in 500 matches.
* The *God Of War* games kinda have this in terms of unlockables. Each one is locked in the main menu and it tells you exactly what you need to do to unlock it. This varies from completing that game's challenge mode to completing the Harder Than Hard difficulty. Good luck with that.
	+ Ghost of Sparta has most of its unlockables purchasable using blood orbs and purchasing them all lets you play as freaking Zeus...but only in the combat arena.
* *Graffiti Kingdom'*s story portion is relatively easy to get through, but obtaining all the attacks and monster cards can be insanely tough at times. (How were you supposed to figure out that defeating a certain number of frogs on that bridge would cause the only monster in the game with Poison Breath to appear?) The only thing you get for obtaining everything is the ability to create anything you want and see all the enemy models in detail.
* The *Gran Turismo* series of games is demanding enough to achieve 100% completion on, but *Gran Turismo 2* was especially noteworthy—due to a rushed port job, it was only possible to recieve a maximum of 98.2% Completion on the official status screen! Sony fixed this, however, and offered replacement discs to people who bought the first run of GT2.
* *Grand Theft Auto* games often give neato whiz-bang prizes for completing 100% of all the optional tasks, tests, and races. All the required tasks for plot completion total around 20%. In *Grand Theft Auto: San Andreas*, the player's childhood home in Ganton is upgraded with spawns for a Rhino tank and a Hydra jump jet.
	+ In *Grand Theft Auto Vice City* you get infinite ammo, upgraded health, maximum armor, the ability to recruit two gang members and a t-shirt that says, "I beat *Grand Theft Auto Vice City* and all I got was this lousy t-shirt." Oh, and an easily accessible Hunter helicopter — toughly armoured and armed with infinite double missiles and a chaingun.
	+ In *Grand Theft Auto IV', getting 100% only removes the ammo cap.*
* Guitar Hero and Rock Band usually require players to complete the entire tracklist in Career Mode so that the same songs can be eventually played in Quick Play, which is probably the most commonly used mode in both franchise. This gets pretty ridiculous in Guitar Hero 3 in particular, where not only is there no co-op quickplay option at all in the PlayStation 2 and Wii versions, the co-op mode has its own tracklist, with several tracks being exclusive to the co-op mode, forcing players to play through the career mode in co-op if they want to unlock all the music. Thankfully, the more recent games in each series have gotten a bit better with this, allowing players to play all songs in quickplay from the get-go.
* In *Harry Potter and the Chamber of Secrets*, if you find all the Chocolate Frog cards (there are about 40), you will be able to open a bonus area. Doing so requires collecting Chocolate Frog cards hidden in challenge/test areas for each of your classes, which must be completed within time limits (although you can replay them) as well as thoroughly searching the castle and grounds.
* In *Hitman 2*, completing missions with a perfect 'Silent Assassin' rating (normally by killing no one other than your mark(s) and firing your weapon only once) will grant you more impressive weapons as a reward, eg. a silenced version of the two silver hardballers that Codename 47 often poses with.
	+ *Hitman 2* only gave you bonus weapons for the first two missions that you complete with a "Silent Assassin" rating; *Hitman: Contracts* on the other hand, gave you a bonus weapon for every mission completed with the rating. A lot of these bonus weapons are pretty damn cool.
* Lucasarts' *Indiana Jones* adventure games had "Indy Quotient" as score. In fact, it was two separate scores: one for what you had gained during the current playthrough, and another one which kept track of all score-giving actions you have accomplished in the game on any play. To gain full score in the latter includes doing things which are nearly impossible or result in an instant death, such as *punching Hitler in public*.
	+ Instant death or not, that's totally Worth It.
* Achieving 100% in *Jak and Daxter* will net you a bonus ending. All ten ambiguous seconds of it.
* *Jed*; interestingly, Challenge doesn't count toward the percentage.
* A similar example is *Jet Force Gemini* for the N64; the player was also required to collect all the "Tribals" in the game to reach the final boss.
* Getting this in *Just Cause 2*, in the PC version at least, is actually *impossible*; the game keeps track of the innumerable number of things you've done out of the innumerabler number of possible things as a percentage, but it seems that the tasks really *are* innumerable, because truly obsessive players have discovered that the game crashes when it tries to load saves that are within a few tenths of a percent of 100%.
* In *Katawa Shoujo*, to get 100% completion you need to fill up your library with every scene possible. If you complete it, you are rewarded with an extra CG in the gallery with a simple picture of the six girls and a thank you for playing the game.
* In *Kingdom Hearts*, you had to lock all the worlds, rescue all the Dalmatians, and beat the Hades Cup to get an extra bonus movie after the credits. A later release of the game required you to do all the Trinities and beat Kurt Ziza as well, but gave you a longer movie.
	+ In *Kingdom Hearts II*, on Standard mode, you have to unlock all the worlds and complete Jiminy's Journal for a movie; however, on Proud mode, you just have to unlock the worlds.
		- Completing that journal includes collecting ALL synthesis items, which are often quite rare monster drops and take a LONG time to find. And then you need to find enough to synthesize all the items too.
		- You also need to level all your drives and summons up to Level 7 (very difficult with Final Form, as it requires defeating 500 nobodies in total while transformed), and then beat the Hades Paradox Cup with 15,000 points. Oh, by the way, all the enemies in the Hades Paradox Cup are at Level 99.
* Getting 100% in *Kirby Super Star Ultra* will get you golden shiny text on your file on the file select screen, a golden rim on the corkboard, and a special Kirby dance video.
	+ As if that's not bad enough, you can unlock the original introduction videos by completing Helper to Hero with all helpers.
	+ Also, 100% in Kirby Nightmare in Dreamland allows you to play through again, but this time as series Badass Meta Knight.
	+ 100% on *Kirby Squeak Squad* nets you a strawberry shortcake. It does nothing. Turns out the cake isn't a lie, But it's pretty damn useless. (Except for Kirby.)
	+ It takes hours of searching to 100% complete Kirby: The Amazing Mirror, even with the Master power.
	+ *Kirbys Epic Yarn* tracks completion in several categories, from characters encountered to fabric textures acquired and so on. The "Flicks" category is the only one you're guaranteed to complete simply by finishing the main plot. And for each category you finish... a bell appears that strikes a unique note. Woo-hoo?
* *KOLM*: There are a bunch of metal plates to collect, each with a letter on it. If you have them all at the end of the game, they spell out It's Kind Of Like Metroid
* Collecting all the masks in *The Legend of Zelda: Majora's Mask* resulted in you receiving the Fierce Deity's Mask at the end of the game. It is easily the most powerful mask in the entire game, but is only usable during boss fights.
	+ Each earned mask also corresponds to a piece of the Segmented Ending, showing the happy ending of whomever you helped in order to earn the mask.
* To get 100% in *The Legend of Zelda: The Wind Waker*, you have to collect a figurine of *every single character in the entire game*. To get a figurine, you have to take a photograph of the character, then go to a particular island and have somebody make the figurine from your photo. Your camera can only hold 3 photographs at once. There are **three hundred** characters in the game, and more than a dozen of these can only be photographed at specific times: if you miss your chance, you miss your shot at 100%, though you can take a New Game+ for a second chance after you beat the game.
	+ Also there are a few characters that only appear when you make use of a Game Boy Advance linked to your Gamecube, and the Tingle-Tuner item, making 100% completion impossible if you do not own a GBA and a Link Cable.
	+ And what is your reward for completing this sadistic sidequest? Nothing. That's right; nothing. You'd think there would be some kind of reward for getting 100%. Anything will do at that point but nope; they give you nothing.
		- To be fair, you do get something: yet another trophy (Link on board of The King of Red Lions), which is unobtainable otherwise. Also, the Tingle-Tuner related trophy is optional (and can be Lost Forever), you don't need it to get the reward trophy.
* *The Legend of Zelda: Skyward Sword* has, along with the main quest, 80 gratitude crystals, all sorts of mini-games (one of which gets the Hylian Shield), many Goddess Cubes, and plenty of upgrades, bugs, and treasures.
* The third *The Legend of Kyrandia* game parodied the scorekeeping mechanic of other contemporary adventure games. The stated maximum score is 911, but the developers have admitted that they pulled the number out of thin air, and it is absolutely impossible to actually reach that score. Points are often awarded for completely irrevelant and nonsensical actions, such as *tripping over a log*.
* The LEGO Adaptation Games (*Star Wars*, *Indiana Jones*, *Batman*) require you to collect a set number of Lego Studs in each level to achieve "True Jedi/Adventurer/Hero" Status, and there are ten pieces of a Lego Minikit scattered around each level.
	+ In *LEGO Star Wars* (1), collecting all of the minikit pieces from a chapter got you a single piece of a larger ship. Getting all Minikits and True Jedi Status for every chapter unlocked the Episode 4 preview.
	+ The amount of "collectibles" has been greatly increased for *LEGO Star Wars II* as compared to Lego Star Wars (1), with red power bricks.
	+ In the DS versions, though, it's made tougher by the fact that in vehicle levels, in order to get a minikit piece, *you must not die*.
	+ This is made easier when you find the 'Invulnerable' red brick. Then you can't die no matter what you do.
	+ The PC version of *LEGO Rock Raiders* features a cinematic of the LMS *Explorer* getting its engines charged up and heading home, one that plays when the player gets a score of 100% on every level. But because one level doesn't contain enough energy crystals to meet its crystal requirement, it's impossible to see the movie without digging through Program Files.
* The Loco Roco games have a goal of obtaining 20 LocoRoco in each level (which is tougher than it sounds), as well as excessive Randomly Drops-Level Grinding to completely build the MuiMui house.
	+ One of the LocoRoco 2 unlockable levels seems to assume that people are going for 100% Completion, much like a Yoshi's Island GBA-exclusive level is (see its entry below). The goal is just downstream (really), while the challenge comes in Wreaking Havok upon realistic Jump Physics to obtain all 20 LocoRoco.
* *Luminous Arc 2* got this, with guild missions, Final Intermission CGs, as well as the Hot Spring Intermissions...
* The first *Mana Khemia* keeps track of how much of the encyclopedia you've filled in. Scaning every enemy, including the ones that only appear in certain endings and the Bonus Dungeon of Hell, and collecting/synthing every item gets you a rumor that adds 30 to everyone's stats. This is made more frustrating by the fact that the bonus dungeon locks up on a regular basis.
* The *Mario Kart*series usually rewards you with extra karts, characters, and tracks when you start getting gold trophies in each cup. The series starts to ramp up the unlockables requirement by not only forcing the player to get star ranks in each cup, but players area also forced to do this for *every cup in every engine class*, which means you will be playing the same 4 to 5 cups at least 4 times each just to get everything.
* *Mass Effect* has Achievements (see Xbox 360) that provide hidden Gamerpics or damage bonuses with certain weapons.
	+ Specifically, there are the "Completionist" achievement (acquired by completing most of the game—not actually 100%, but including most of the sidequests), and the six different ally achievements, which require you to have a particular character in your squad for almost all of the game. The achievement for Liara is particularly tough to get, since you have to deliberately avoid sidequests in the early part of the game so you can advance the plot enough to rescue her first, then go back and do the quests you avoided once you have her on your team.
		- Of those six ally achievements, the Arbitrary Headcount Limit will likely prevent you from achieving more than two at once, meaning you'll need at least three playthroughs to get those. This is just as well, since you'll need more than one playthrough in order to get the Power Gamer achievement (reach level 50) and likely more than two to get the Extreme Power Gamer achievement (reach level 60). The game does have New Game+, but there are also achievements for heavily using certain abilities which aren't available for all classes. You'll probably need to play through the game at least four or five times in order to get all of the achievements.
	+ Even aside from these metagame achievements, there are several in-game Collection Sidequests that require you to visit a large fraction of the explorable galaxy and often go out of your way when exploring uncharted worlds in order to complete them. Similarly the "Scan the Keepers" sidequest, which while confined to a single large space station, requires exploring nearly every nook and cranny of said station.
* In *Maximo*, there is a secret level named "Mastery" that requires you to get 100% completion to enter.
* In *Medieval 2: Total War*, completing the Long Campaign is basically the highest achievement you can get, it involves taking over about one third of the known (at the time) world, and as a reward you get a victory cutscene. However it is possible to continue playing, and take over the entire known world (this takes a LONG time), and what do you get for this? Nothing, the game just keeps going, but with no-one left to fight. Oh the futility of war.
* In *Mega Man Powered Up*, if you chose to play through the game in New Style, you can play through 13 stages in all. Not too bad, right? Then there are the Difficulty Levels, which are 3 in all. And it's available in all the stages, totaling up to 39 possible stages. Not daunting enough? Now factor in every Secret Character in the game: Cut Man, Guts Man, Ice Man, Bomb Man, Fire Man, Elec Man, Time Man, Oil Man, Mega, Roll, and Proto Man. That's twelve characters in all (Mega Man, Mega Man S, and Mega Man C are all considered the same character, as is Roll and her various costumes). Combined with the aforementioned stages and difficulty levels, you'd end up with ***468 stages*** to complete to achieve 100%! Old Style? No difficulties, no additional characters, all you have to do to get 100% here is to clear all 10 stages. That's it.
* *Mega Man 10* takes this approach literally, giving you a percentage number that corresponds with how many challenges you have completed. The normal game is relatively short, and will take 5 or 6 hours to complete, less for Mega Man veterans. But the challenges will take many more hours to complete. Essentially, the game doubles or triples in length if you go for 100% Completion. Getting a 100% requires you to beat all challenges with a Gold Medal, which requires you to beat each challenge without taking any damage, among other things. Your only reward for doing this is showing an S Rank on the challenge screen.
* Completing all 300 missions in *Metal Gear Solid: VR Missions* will show a picture of Metal Gear Ray, the mecha from the next game, which cannot be seen again once you save your progress after seeing it.
	+ *Metal Gear Solid 3: Snake Eater: Snake Eater* has two special items for the completionist in you. The first is the Infinity Facepaint, only awarded to those who finish the game with a perfect score or capture a small invisible animal and keep it alive until you finish the game. The other is the Stealth Camo, only rewarded to those who go through the whole game without killing anyone or being spotted or to those who can find 64 tiny, really well-hidden green frogs scattered around the game.
* A series-long example: Each game in the *Metroid* series since *Super Metroid* has a percentage. While earlier games in the series, including *Super Metroid* itself, gave different endings based on completion time rather than percent, percent has now become a factor in determining which ending you get, actually displacing time in the Prime sub-series for technical reasons. *Zero Mission* actually features two prizes for getting 15% or lower!  9 items are required to complete the game, and it's generally recommended you fill five of the remaining slots on Super Missiles and Energy Tanks, with the last slot going to either Screw Attack or Speed Booster. Either way, you'll need to have mastered the game and Bomb Jumps.
	+ - This factor actually varies from version to version (if you're playing the game on Hard). The European version can be completed on both Normal and Hard with 9% but the Japanese and US versions require a 10% completion rating on Hard due to a quirk at the end of the game concerning destructible blocks.
	+ Players of *Metroid Prime Trilogy* can get a whopping 300% completion, or 100% per game.
* *Nethack* is a difficult enough game to begin with, but in addition it has conducts, which forbid key strategies in the game such as praying, reading, eating, and killling a monster directly. There is also extinctionism, in which you kill *all* of the monsters in the dungeon (they stop reappearing when you kill enough). 100% completion would be ascending while keeping all these conducts, achieving full extinction, and getting a final maximum score of 2147483647. This has never been accomplished and probably never will be (some have come close)
* Going so Over the Top in this regard it's not funny, *No More Heroes* for the Wii features a set of "trading cards" that the player can collect. There are 50 cards on the first run through of the game, each bearing the picture of a wrestler's mask. There are in reality a total of 150 cards in the game, *which must be replayed a minimum of three times from clear files* to achieve 100% Completion. This fits in with the game's over-the-top nature, as the "hero" is a obsessive *otaku*.
* The Oddworld games give you a bonus ending if you save all the mudokons in the game.
* In *Okami*, collecting all 100 Stray Beads nets you a Game Breaker for your New Game+. Completists will also want to acquire at least one of every type of fish and treasure as well as feed 100% of all animals. On the topic of that last one, there is one dog that can be Lost Forever, though it's not out of the way. When you go to the past Kamiki Village, feed the dog in the village.
* Billy Mitchell became the most famous gamer on the planet for being the first to complete a "perfect game" of *Pac-Man*. This consisted of not only clearing every level that could be completed (255), but eating every fruit and ghost in every single level.
* To get the best ending in *Painkiller*, you not only have to beat the game on Nightmare difficulty, you also have to beat the card condition on each level and unlock their respective cards...which unlocks Trauma difficulty, beating which finally rewards you with the best ending.
* Subverted in *The Path*: It isn't possible to collect all items on any run-through with any single girl, and because some events unlock items and events only accessible by another girl, it's not possible to get 100% completion on the first complete playthrough. And even after collecting all secret flowers and inventory items, visiting every site, unlocking every secret room, and encountering The Wolf with all girls, the player is rewarded with a purely arbitrary, semi-random letter grade between D and B...you can never get an 'A' and there will always be some items counted as not discovered.
* Maxing out all your social links in *Persona 3 Portable* or *FES* gives you the colorless mask. With that, once you reach level 99, you can fuse Orpheus Telos, a Palette Swap of your first persona, but one that is strong against every attack in the game (except Almighty attacks), and can inherit any move in the game. With a lot of work, time, and intensive planning, you can create persona with the eight best moves in the game, which would normally require 8 different persona. Of course, maxing all the social links requires an absolutely perfect understanding of the games relationship sim mechanics, and fighting normal gamer instincts to move the plot forward for as long as possible, as you just don't have the time to succeed otherwise. Or in other words: a guide. He is also necessary to get 100% of the persona compendium, meaning you've had every persona at least once, although achieving that gives you absolutely nothing. Completing all of Elizabeth's side quests gets you nothing, but completing certain ones are necessary to get all the items and persona in the game.
* The Trophy system for Play Station 3 games (which works similarly to Xbox 360's Achievements) has a whole tier—Platinum—that represents collecting every other trophy in the game. In some games, there is a separate trophy for completing 100%.
* Taken to ridiculous levels in *Pokémon Ruby and Sapphire*. Completing your Pokédex means trading across seven different games and two systems: *FireRed*, *LeafGreen*, *Ruby*, *Sapphire*, and *Emerald* on the Game Boy Advance, and *Pokémon Colosseum* and *XD: Gale of Darkness* on the Game Cube. After that, going to Nintendo events is required for the infamously impossible-to-catch Mew, Celebi, Jirachi, and Deoxys (though Celebi can be obtained without an event in Japan), although these Pokémon aren't required for the game's recognition and you'll still get the diploma without them.
	+ Completing the Pokédex just awards you with a star on your Trainer card. If you really want to get technical, 100% completion would involve the player getting all 5 possible stars on their cards. This includes challenges such as winning a Master Rank Super Contest (DPPt), stealing 50 flags from friends in an underground minigame and winning 100 battles in a row at the Battle Tower (just so you know, after around 50 the game begins fielding teams full of legendaries and cheating like no tomorrow).
* In *Psychonauts*, not only can you clear all the figments, emotional baggage, and cobwebs from every in-brain world, and collect the items from the scavenger hunt, but it's also fun to try to talk to, punch, burn, telekenetically lift, and read the minds of every single character you come across.
	+ And all the characters will have something different to say, because The Dev Team Thinks of Everything!
	+ The level total actually goes up to 101, because of one bonus level given for clearing a combat mini-game. Doing this on the Steam version gets an achievement titled Math is Hard.
* *Radiata Stories* has the interesting quality of having at least 120 characters that can join your party, all of which must be added to your Friends List through various means. It's impossible to get all the characters on one go, as the story branches halfway through the game and some characters are only found on one path or the other. When you do get every single character, you get an extra little picture on your Friends List. Hooray?
* In *Ratchet and Clank Up Your Arsenal*, you had to collect fifteen trophies, which pretty much required doing everything. Doing so earned you access to the Insomniac Museum, filled with concept art and other behind the scenes goodies.
* The first *Rayman* game requires 100% completion (breaking all the Electoon cages) to get to the final level.
* The reward for 100% completion in *Red Dead Redemption*...is clothes. Specifically, it's a Government Agent suit, which lets you do anything you want without being attacked by cops. However, that doesn't stop the citizens from firing back.
* In *Resident Evil 3: Nemesis*, collecting every single file *in order* grants the Jill's diary, a secret file that explains some of the events that occurred during the Time Skip. Annoyingly, each file has to be read as soon as it is obtained to get this.
	+ However it's incredibly easy to screw this up due to optional paths and a room containing two files at once, with no indication of which one comes first.
* To achieve 100% in *Riviera: The Promised Land*, you have to view all of the CG scenes, collect all of the items, use all of those items' Overdrive Moves, and defeat the Bonus Boss after completing the game. And to get all CG scenes, you have to finish the game SIX times!
* In *Rollercoaster Tycoon*, if the player wins/completes all of the scenarios, a special, unbeforeseen park is unlocked.
* *Scaler* has two endings, the good ending with both the main character and his dad returning from the alternate world, and a bad ending where his dad doesn't make it back. Completing the game with anything less than 100% gives you the bad ending.
* *Scarface the World Is Yours* needs you to buy all the Exotics, collect all the Femme Fatales, wiped out all the gangs in Miami and completed the extra missions on the Islands. Fortunately, there is no need to pass all the races. Achieving this let Tony summon the Femme Fatales as bodyguards.
* Getting all 50 Oboro coins in the PS2 version of *Shinobi* will unlock the final piece of artwork in the Concept Art Gallery, as well as an extra stage in Trial Mode that is nothing more than a glorified training stage.
* Sierra adventure games like Space Quest have a points score of "X out of X" at the top of the screen. Some of the puzzles have multiple solutions, with the most difficult solutions required to reach a perfect score.
	+ This becomes even more complicated because Sierra is the master of the Last Lousy Point.
* *Sigma Star Saga* would acknowledge if you had found all of the Gun Data when beating the game.
* In *Siren*, getting 99% completion of the archives (which aren't actually listed as a percentage, but there are exactly 100 entries in the archive, leading to the same effect) unlocks two extra videos. One of them is just a filler that shows what one of the characters was up to during a gap when we didn't hear from her in the course of the normal game... but one of them gets you 100% completion and shows the event that caused everything that happened in the game. And getting 99% completion is basically impossible without a guide, as archive items are hidden throughout all the game's stages, and sometimes don't stand out, or require you to do odd things to find them.
* *Sly Cooper* 100% nets you a "making of" movie.
	+ In Sly 3, 100% earns you "a music video". It's actually totally worth it. Watching it on YouTube doesn't do it justice.
* Getting every emblem in *Sonic Adventure 2 Battle* unlocks a 3D version of Green Hill Zone. Unfortunately, that means completing every mission with an A rank (some of which are nigh impossible, such as getting 100 rings in a set amount of time when there are only 114 rings in the level), surviving three boss rushes, one racing mini game, and beating all the races and all the levels of karate with your chao.
* To this day, it's unclear to me what the reward (if any) for getting all the secret tokens, buoy tokens, races etc etc etc in *Spider-Man 2: The Movie* is. Because it seems, to all intents and purposes, to be frelling impossible. I recorded several straight days worth of play time, and was still only about two thirds of the way there, having also completed the whole game, and gotten all the other achievements etc.
	+ Near the beginning of the game, snarky narrator Bruce Campbell tells you that if you activate all of the 200+ Hint Markers (icons that provide hints spread throughout the city), he will say something different every time you activate them again. Several hours later, after activating the last marker, you activate it again, expecting more snarky advice. And Bruce says..."something different". Yes, the phrase "something different".
	+ The third game has a similar issue. Photographing all the bad guys, beating gangs, collecting spider tokens to unlock a black suit you no longer have any goddamn need for because the tokens only appeared when you took down Venom for the last time...perhaps the worst is the meteorite fragments, which unlock you a large yellow "CONGRATULATIONS" sign.
* Each game in the original *Spyro* trilogy brought different rewards for 100% completion: The Big Bad's treasure vault in the first game, an unlimited supercharged flame breath in the second, and a final level with tons of treasure and the last dragon egg in the third.
	+ In Spyro 2, after you get that eternal superflame, save the game, start the game over (in that same file), and dominate EVERYTHING!
	+ The third one had what is possibly one of the most satisfying of all 100% completion rewards. After you collect every gem and every dragon egg, you meet Moneybags, the irritating bear that you had to pay so many precious gems to get him to do things like lower a bridge or start a fan. He offers to sell you access to the final level for the cost of every single gem you've collected. What follows is the player chasing him around, ramming into him horns-first until he coughs up every last gem he took from you.
	+ *Season of Ice* took this to the extreme: you had to have 100% to finish the game.
	+ Also from Spyro: Skill Points. They are like Achievements before Achievements. Getting all of them in Spyro 2 gave you the "Epilogue" and some concept art for things that didn't make it.
* *Star Ocean: Till the End of Time* features "battle trophies"; as you unlock more, you get things like more difficulty levels and extra characters for the pseudo-fighting game Mini Game. The challenges include things like beating bosses within a particular amount of time, or at low levels, getting X number of combos, walking X number of game-feet, playing for X amount of time, etc.
	+ One of the trophies is for defeating the last Bonus Boss in under two hours on the highest difficulty setting. This is actually quite difficult to accomplish.
	+ Star Ocean: The Last Hope also has Battle Trophies. This time around, however, they are character specific; each of the 9 playable characters have 100 trophies to obtain, for a total of 900 Battle Trophies.
* *Strong Bad's Cool Game For Attractive People* always has that *one thing* that you're not going to stumble across in normal play and that you can't go back and get later. In episode 2, it's insulting Strong Sad that's likely to trip you up. In episode 3, There's an "expression of affection" in a line that is only heard if you have high hint mode turned on.
* In all of the *Suikoden* games, you get the true ending only if you have all 108 Stars of Destiny in your party.
	+ Except III, in which all you get is the ability to play through the game as the antagonist, though part of the Where Are They Now? Epilogue changes.
* *Super Bomberman 5* keeps a percentage on your save file, which represents how many of the game's 100 levels you have cleared. Good luck doing this without a guide; not only do you have to be skilled at Bomberman, but you must also figure out the paths to levels you haven't reached yet. The game's highly non-linear. Each stage can have up to five different exits, and boss stages look identical save for the fact that they'll take you to different starting points in the next world.
	+ After you acheive 100% Completion, you can go for 200%. It's easier this time around since high-quality powerups will appear more often.
* As stated in the quote, Mario has taken to this since *Super Mario 64*. In *Super Mario Galaxy*, there are 120 stars, but you only need 60 to get to the ending. In fact, several stars are only available after getting the ending the first time. Furthermore, 100% Completion demands you to get all stars again with Luigi. After fighting the final boss again, you unlock Grand Finale Galaxy, for both Mario and Luigi. All in all, you'll have to beat the final boss *four times* before you're done, and collect a total of 242 stars!
	+ *Super Mario Galaxy 2* continues the trend. After beating the game, you unlock the World S. Getting all the stars and Prankster Comet stars across all seven worlds gets you 120 stars. You must then beat the game a second time to unlock the Green Star challenge, which gives you *another* 120 stars to collect. Then after that, you unlock the Grandmaster Galaxy, which contains the final two stars. Like the last game, there are 242 total stars.
	+ Super Mario Sunshine is probably the hardest 100% to get. Several stars are gotten in levels that can qualify as Platform Hell and That One Level, obtaining lots of Collectables that is a challenge by itself, and of course you can't get them all until you beat the game. Sunshine might even be harder to get 100% in than Galaxy 2 because of the very gimmicky FLOOD.
* The ending of *Super Mario Land 3: Wario Land* is determined by how many coins and treasures Wario has picked up during the game—specifically, this determines how big a castle he can buy. Finishing with 99999 coins *and* all the treasures results in getting the entire *moon*.
* In *Super Mario World*, there are seventy-one levels (not counting Bowser's castle) with ninety-six possible exits between them. Your game file is updated to reflect not the percentage of the game or number of levels you've cleared, but the number of exits you've found. When you get ninety-six, a little star appears in your save file. In addition, for completing the Special World, you are treated to a Halloween-themed palette shift in the world map, and in the levels themselves, the Koopas wear giant Mario masks instead of shells, the piranha plants become jack o'lanterns, and the Bullet Bills become pidgits. (Other ports vary this change in some way, but the general idea is intact.)
	+ The Game Boy Advance remake adds another challenge: collecting all 5 Dragon Coins in each level. Your reward for doing this? The Dragon Coins will turn into Peach Coins.
	+ The star in the original game was actually added to the American version.
* In *Super Mario World 2: Yoshi's Island*, getting 100% on every level in a world opens up both an additional level and a bonus game which can be played an infinite number of times for extra lives and/or inventory items. Achieving 100% completion, however, requires collecting twenty red coins, thirty star points, and five flowers, which is *insanely* tougher than it sounds, because it's not the type of game where you can miss one and go back in and get it later. *You have to pick everything up in one go.*
	+ One of the GBA exclusive levels, World 5-Secret ("Items are fun!"), actually seems to *assume* that everyone is going for 100 percent completion. The goal ring is in the second screen and requires almost no effort to reach; the challenge comes in figuring out where all the coins and flowers in the level are.
	+ What's more, stars are essentially your Hit Points, meaning that, while exceptions can be made, Hundred Percent Completion requires you to take no damage late in the level (when there are no more stars to find) or when fighting a boss. The original let you collect Star Cards, which could increase your star count any time outside of a boss, cutting the player some slack, but *Yoshi's Island DS* has no such thing.
* Super Meat Boy has a percentage for each world. Getting 100% in a world means completing all levels (both Light and Dark Worlds) with an A+ rating, defeating the boss, getting all the bandages, and completing all warp zones. There's even an achievement for getting 100% on all worlds. The glitch levels don't count towards percentage, though.
* *Super Smash Bros.. Melee* has nearly 300 trophies (290, plus three special ones), special items that you receive by fulfilling certain conditions in-game. Each trophy is modelled after a character, item, or setting from a Nintendo game, and comes with a little bit of trivia regarding the item it represents.
	+ *Brawl* adds stickers to the mix. SEVEN HUNDRED OF THEM. Oh, and 544 trophies. And 128 challenges. Here's a list of all the unlockables.
* Like most *Tales* games, *Tales of Symphonia* has an item completion book which records all the items that come into your inventory. It takes two whole playthroughs and going through another 85% of the game before you complete the listing. And that was only if you were very careful in manipulating relationships between characters.
	+ In addition, there's also the "Monster Book", which records every monster you encounter. Since there is one point where depending on which choice you made at an earlier time the boss is different it will take at least 2 playthroughs to record every enemy. The one good thing is that, contrary to popular belief, you don't need to record all the stats (which requires you to have a certain character use a certain item on each enemy). Your reward? A title for one character.
	+ The more recent *Tales of the Abyss* has something similar. The reward for completing the item list? A title for a single character that comes with a small stat boost.
* All *Thief: The Dark Project* and *Thief II: The Metal Age* missions track whether you have all the loot and all possible pickpockets; the latter also tracks whether you have found all the secrets in the mission.
	+ In *Thief: The Dark Project*, "Down in the Bonehoard" has an optional quest to find all the golden bones and return them to their tomb. You are rewarded with some extra equipment.
	+ In *Thief: The Dark Project*, "Return to the Cathedral" has a very difficult to avoid objective added partway through the mission; killing all the Hammer Haunts in the level.
	+ In *Thief: The Dark Project*, "Strange Bedfellows" has an optional extra objective; if you kill any bugbeasts, then you have to kill all the bugbeasts in the mission, even if this means backtracking to the beginning of the level to kill the first bugbeast you encountered.
	+ Partially averted in *Thief II: The Metal Age*, "Eavesdropping". You have to steal one of the keys lying around the level, copy it, and return it to its original location, but *which* of the (identical) keys is set randomly. Consequently, you do *not* want to collect all the keys before eavesdropping on the conversation that tells you which one you need...
* Several of the *Tomb Raider* games have secrets (via items or just hidden rooms) which usually contain extra health and ammo. While some of the games' secrets are nothing but bragging rights when you get 100%, the 3rd game unlocks a bonus level for you to explore and beating that gets you all guns with infinite ammo for any level you play over.
* The *Uncharted* games play with this, dotting treasures around the world for you to find. 100% completion requires 61/60 treasures in the first game and 101/100 in the following two. The rewards are things like weapon select, character skins, making of videos and the like.
* Visual novels generally at least allow the player to unlock CGs in a gallery section as they are encountered in the game, requiring the player to seek out all the branches in order to clear them all. Sometimes there is a completion percentage, other times the player makes do with simple blanks. Unlocking all the CG usually doesn't do anything else. Unlocking enough (or all) of the Multiple Endings, however, usually does.
	+ *Fate/stay night* keeps track off the (numbered) bad ends with tiger stamps. Collecting all the stamps and completing all the endings nets you a short video and a new title screen. But getting the bad endings is its own reward anyway.
		- Getting all the deaths and every ending (1 Fate, 2 UBW, 2 HF) in the Realta Nua Updated Rerelease unlocks a wonderful new ending to the Fate route, which before had only had a Bittersweet Ending. Best use of Together in Death this troper has ever seen.
	+ Reaching all the endings in *Tsukihime* unlocks the epilogue 'Eclipse.'
	+ There's an actual meter for it in *Fate/hollow ataraxia.* Reaching 100% unlocks a bonus scene.
	+ *Aoi Shiro'*s image gallery helpfully gives the percent CG collected for each character and overall. Another screen keeps track of all the endings by marking them with pearls as they are reached.
* *We Love Katamari* takes this to the point of insanity: beating the game once opens a bonus level in which you are asked to collect *one million roses*, **no more than 10 at a time**. (Thankfully, you aren't required to do this all in one sitting.) Completing this task unlocks some slight graphical tweaks (roses everywhere) and a new song.
	+ In most Katamari games, there's a catalog of all the items you can roll up, with a brief description of it by the King of All Cosmos. It doesn't contribute to overall game completion and is totally optional, but many completionists strive to fill it in, which can be a very daunting task.
* Most *Wild ARMs* games will offer special Ex. Game rewards for completing particular challenges, such as opening every chest in the game, filling in every spot on the world map, getting to Level 100 with all characters, or beating particular bosses.
* *The World Ends With You* has 22 secret reports, 96 Noise reports, 472 items, and 304 pins to collect (and a Speed Run Boss Rush which only counts on tougher difficulties). Completing each set gets you a star rank for that collection and a new character on the save screen. Collecting all the secret reports also unlocks The Stinger.
	+ Then there's your ESP'er score... You gain one point for each battle cleared and each item bought worth more than 10,000 yen. And you need *exactly* 10,000 points in the US version to achieve God rank. One more and you're back down to Demon.
* *World of Goo* has Obsessive Completion Distinction for individual levels and one cannot call oneself a true Goo Master unless one has achieved this on every level of the eponymous world *and* built a ridiculously tall tower in the sandbox environment.
* Xbox 360 games have Achievements, which boost a player's Gamerscore. Some Achievements also unlock extras in the game. Extremely recent games such as Guitar Hero 5 add Unlockable avatar items from achievements.
	+ Note that some Achievements are nigh-impossible to unlock. See the previous entry on *Gears of War* or see why *Rock Band* is the trope namer for Bladder of Steel.
