# Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!

Pokémon: Let's Go, Pikachu! and Pokémon: Let's Go, Eevee! are 2018 remakes of the 1998 Game Boy role-playing video game Pokémon Yellow. They were developed by Game Freak and published by the Pokémon Company and Nintendo for the Nintendo Switch. Announced in May 2018, Let's Go, Pikachu! and Let's Go, Eevee! were released worldwide for the Nintendo Switch on 16 November 2018. The games are part of the seventh generation of the Pokémon video game series and are the first main series installments to be released for a home game console. They feature connectivity with the mobile game Pokémon Go and support an optional controller, the Poké Ball Plus.
Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! were first announced at a Japanese press conference in May 2018, with the intention for the games to bring in newcomers to the series as well as cater to old fans. They were also meant to appeal to a younger audience; for this reason, the games incorporate elements from the anime, similar to Pokémon Yellow. They received generally favorable reviews from critics, with praise directed at the accessibility and charm, while criticism was directed toward the motion controls. The games have combined worldwide sales of over 15 million as of December 2022, making them one of the best-selling games for the system.

## Gameplay

Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! are set in the Kanto region and include the original 151 Pokémon in addition to their respective Mega Evolved forms from Pokémon X, Y, Omega Ruby, and Alpha Sapphire and their Alolan Forms from Pokémon Sun and Moon.
Let's Go, Pikachu! and Let's Go, Eevee! feature common elements of the main series, such as battling non-player character Pokémon Trainers and Gym Leaders with caught Pokémon creatures. However, when facing wild Pokémon, instead of battling them with the traditional battle system like in past games, the catching of Pokémon uses a system that is reminiscent of the mobile spin-off game Pokémon Go. By using the motion controls of the Joy-Con controller or Poké Ball Plus peripheral, players can throw berries to pacify a Pokémon or Poké Balls to attempt to capture it. The action can also be performed with a button press when the Joy-Con controllers are docked to the console or in handheld mode, but this still requires using motion controls to aim. If a player uses motion controls, the catching of Pokémon is based on the player's timing rather than accuracy. Although it is possible to miss a throw, the ball is almost guaranteed to make contact with the Pokémon. One notable difference in Let's Go, Pikachu! and Let's Go, Eevee! is that wild Pokémon are visible from the overworld, rather than as random encounters in grass or in caves like in previous main series Pokémon role-playing games. To start an encounter with a wild Pokémon, the player must simply approach the Pokémon in the environment.
The games' control scheme is designed to only require one Joy-Con per player, and the games support cooperative multiplayer. If another player shakes a second Joy-Con, they can join the current player and are able to participate in battles with Pokémon Trainers and wild Pokémon encounters, allowing them to aid in the catching of wild Pokémon. When playing multiplayer, Trainer battles become battles of two Pokémon against one, and in wild encounters, there is the possibility for each player to throw a Poké Ball at the same time, doubling the chances of capturing the Pokémon.
Depending on the version, players start with either a Pikachu or an Eevee, which sits on the player character's shoulder in the overworld. This mechanic is similar to the "walking Pokémon" mechanic first introduced in Pokémon Yellow, in which Pikachu follows behind the player character throughout the game. The player's partner Pokémon wiggles its tail when they are near a hidden item, and it can be dressed up for further customization. Similarly to Pokémon HeartGold and SoulSilver, players may also choose a Pokémon to follow them, and some larger Pokémon can also be ridden, a mechanic first seen in Pokémon X and Y and later expanded on in Sun and Moon.
Since Pokémon X and Y, experience points are rewarded to Pokémon by not only defeating opponent Pokémon but also catching wild Pokémon. However, in Let's Go, Pikachu! and Let's Go, Eevee!, experience points rewarded by catching wild Pokémon are affected by various multiplier bonuses depending on the timing of the throw and the technique used to throw the Poké Ball, such as performing an overarm or underarm throw. The games also introduce new items called "candies", which are used to power up a Pokémon's statistics, such as hit points (HP), Attack, Defense, Special Attack, Special Defense, and Speed. Different types of candies are awarded to players who transfer their Pokémon to Professor Oak via an in-game storage box. "Combat Power" (CP) also returns from Pokémon Go.
The evolution mechanic from previous games returns in Let's Go, Pikachu! and Let's Go, Eevee! However, as with Pokémon Yellow, the player's starting Pikachu or Eevee cannot evolve; only other Pokémon that the player has caught, including ones of the same species as the partner Pokémon.
Some features, like Pokémon breeding and HMs, are absent from the games.

### Connectivity

Players can trade Pokémon and battle other players both locally and online, with online features being simplified in comparison with previous games. Some features—including the Global Trade System, Wonder Trade, and Battle Spot—are absent from Let's Go, Pikachu! and Let's Go, Eevee!. In order to connect with others to trade or battle online, players must use a code composed of three Pokémon glyphs, selected from a total of eight. When two players enter the same code, they are connected to trade Pokémon with or battle each other. A subscription to the Nintendo Switch Online service is required to use online functionality.
Although Let's Go, Pikachu! and Let's Go, Eevee! feature integration with Pokémon Go, this is optional. Players can transfer the original first generation Pokémon and their respective Alolan Forms from Pokémon Go to Let's Go, Pikachu! or Let's Go, Eevee!. They then appear at the Go Park—an in-game location where the player can explore and interact with or catch Pokémon that are walking around. Pokémon with higher CP or levels are harder to catch, in that the catch attempt has a higher chance of failing. Users are also able to exchange unspecified "gifts" between Pokémon Go and Let's Go, Pikachu! or Let's Go, Eevee!.

### Poké Ball Plus

The games support the Poké Ball Plus, an optional controller shaped like a Poké Ball which features an analog stick, motion control support, HD Rumble feedback, and lighting effects. The analog stick doubles as a capture button in case the player does not wish to use the motion controls. Pokémon can also be transferred to it, in a similar way to the Pokéwalker. During Nintendo's E3 2018 Nintendo Direct presentation on 12 June 2018, it was revealed that the Poké Ball Plus would come with a Mew that can be transferred to the games.

## Plot

The setting and story remain largely the same as Pokémon Yellow, complete with the inclusion of anime-exclusive characters.
The eight Gym Leaders and the members of the Elite Four return, as well as the antagonist faction Team Rocket, including Jessie, James and Meowth, from the anime series. Unlike the anime series, Meowth cannot speak the human language and is given his own Meowth cry. There are eight gym badges. The Boulder Badge, The Cascade Badge, The Thunder Badge, The Rainbow Badge, The Soul Badge, The Marsh Badge, The Volcano Badge, And The Earth Badge. Players need all eight gym badges to get into the Kanto Pokémon League in the Indigo Plateau and challenge the Elite Four.

## Development

Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! were unveiled during a press conference in Japan on 30 May 2018. They are primarily aimed toward a younger audience and those who are new to the Pokémon franchise. At the time of announcement game director Junichi Masuda mentioned that the games had been in development for around two years. Masuda also stated that he considered the games to be remakes of Pokémon Yellow, explaining that Yellow "resonated" best with younger players because it incorporated elements from the Pokémon anime television series. According to Masuda, he decided to make Eevee the mascot of the other game due to its popularity and abundance of fan art. He had previously considered Psyduck but ultimately changed his mind, stating that it was due to Psyduck having a headache.

## Release

The games were released internationally on 16 November 2018. Bundles of the games with the Poké Ball Plus controller were announced, as well as a Nintendo Switch console bundle, including the games, brown and yellow colored Joy-Con, and a dock with artwork of Eevee and Pikachu. On 21 September 2018, Amazon began offering pre-orders for the Let's Go, Pikachu! and Let's Go, Eevee! Switch bundle.

IGN's Miranda Sanchez praised the game's catching mechanic which drew inspiration from the gameplay of Pokémon Go. She mentioned that she could "prioritize catching the Pokémon I actually wanted" and avoiding undesired ones thanks to the games' new overworld view of the Pokémon.
The implementation of the motion controls has been criticized by some sources for reducing accessibility to some players with fine-motor or physical disabilities.
