When I was a kid I hated the Xbox, hated Halo, and hated how it seemed to create a new model for playing games. It was released when I was in middle school, and I remember there being a sudden and abrupt shift in what kind of gaming mentality there was.

Prior to the Xbox, console games were largely focused on lush, whimsical landscapes with mechanics that required some puzzling to figure out. At least, the games that kids played, anyway; I know Unreal Tournament and Doom and Quake were big, but looking back I think those games all had a whimsy to them as well. The arsenal in Unreal is way sillier than anything Halo's ever had to offer (even Halo's energy sword seems kind of rote). And the major titles on the N64 and Playstation and Dreamcast were titles like Mario and Sonic and Crash Bandicoot – colorful worlds, puzzles often based on platforming. Developers like Nintendo and Rare had a knack for creating controls and visuals that seem to reward you for getting into them, so that even Rare's Goldeneye 007 felt like an utterly silly game. (Proximity mine in the toilet!)

When Halo came out, it was immediately apparent that this was Microsoft's grand new vision of gaming – "realistic" graphics, self-seriousness, achievements, and an ugly competitive edge. My memories of Halo are almost all multiplayer, obviously: generally, six kids sitting by a machine, two of them unhappy because they sucked and consequently were cycled out every other game, meaning they didn't get practice time either. The local teen center turned into a place where a bunch of bro-types would hook up their Xboxes and play each other all night, screaming at one another between rooms. The TV that was used for movies got co-opted into another Xbox resource, so eventually the whole place became a Halo pit. And online Halo (which started with 2, if I recall correctly) changed the dynamic yet again, in a way that's familiar to all of us: kids cussing at one another, players generally acting like little shits.

Some of that all would have happened without Microsoft's "Xbox is a manly console for men" marketing push. But you can absolutely look back and say that Microsoft influenced developers in a bad way. Sony made a push to "cut Microsoft off" with titles like God of War, which are similarly quote-unquote epic. Halo opened the door for Tom Clancy games, Call of Duty, Assassin's Creed, on and on. A number of older game developers decided, when they made the change from 2D to 3D, to pursue a similarly "gritty" realism. Now there's a gaming culture wherein genres are solidly defined and there's excruciatingly little variation between game mechanics, visual style, or design mentality, at least in the AAAs. And it's because of how relentlessly Microsoft pushed to divide the market.

The old designers either shifted their styles along with this, or they ran out of steam. Sega hasn't made a good game in over a decade – I won't even blame that on their pursuing a "mature and edgy" vibe with the Sonic franchise, though they seem to think that's what gamers want. They just ran out of ideas for where to take Sonic. Rare had a couple of late-era successes, mostly Viva Pińata, but the only thing they've done in five years is Kinect Sports games. And Nintendo? They still stick to their old style, but this many years on Nintendo's flaws as a game developer are showing. Aspects of their games which were totally forgivable when they were building for N64 or even Gamecube are starting to feel like irritatingly deliberate decisions on their part now. And you know what? That would be okay if Nintendo didn't sometimes feel like the only company still pushing that particular aesthetic. If they were one company among many, it wouldn't matter so much, but they're singlehandedly trying to push against the currents of every other game developer on the planet, and it's increasingly becoming clear that they're just not good enough to carry that all by themselves.

Obviously, this is a view of just a limited slice of gamer culture. Indie games absolutely borrow from the old-school design mentality more than they do from the Halo mindset; I've seen more whimsy and fun in a single Humble Indie Bundle than I've seen appear on the Xbox 360 since its release. Even there, though, you can feel the influence somewhat, and it's spoiled some games that I really wish I could have enjoyed (namely Bastion). And you do have both occasional lighthearted breakouts (Katamari Damacy) and games that use the self-serious mentality to incredible effect (Demon's Souls). This is a fad which will pass with time, though I'm not so pleased at the thought that our next big wave of developers are the ones developing for mobile and Facebook. Angry Birds and Farmville are not a fun influence. But that's just the way it goes. There'll always be good stuff if you know how to hunt for it. I just miss the fact that for a decade or so, the best games were at the top of the heap or close to it. I don't know if I realized how lucky I was as a kid until that ended. The 90s were a great time to grow up a young gamer.
