Pokémon Let's Go Pikachu and Pokémon Let's Go Eevee (ポケットモンスター Let's Go! ピカチュウ・Let’s Go! イーブイ Poketto Monsutaa Rettsu Go Pikachuu & Rettsu Go Iibui) are two games of Generation VII set in the Kanto. These two games are remakes of Pokémon Yellow Version, which was first launched in Japan in 1998. The games are designed with the sole intent of being played by new fans who have only played Pokémon GO, rather than veteran players.
- The player can connect their smartphone with Nintendo Switch to exchange Pokémon from Pokémon GO to the game.
- As the games are remakes of Yellow, they are heavily inspired by the anime. Like Yellow, the three Kanto starters are received as gifts from in-game events based on episodes of the anime. Additionally, Jessie, James, and Meowth return to the series for the first time since Yellow, and play a larger role than they did in Yellow.
- The player can customize their character, and the appearance of Pikachu or Eevee. While Pikachu, Eevee, and the player character can change into matching outfits, customization of the Pokémon also includes things such as gender and hairstyles.
- Female Eevee now have a heart-shaped pattern on the tip of their tails, similar to Pikachu’s on a heart-shaped-based tail related. Thus, making it the first Pokémon from an earlier generation to receive a gender difference in a newer one lately since Generation IV, where gender differences were introduced.
- The feature of catching wild Pokémon is modeled after Pokémon GO. Instead of battling wild Pokémon, the player character only needs to throw the Poké Ball at them. This involves the Switch's motion controls.
- Legendary Pokémon are still fought in the wild.
- These two Games also feature two-player simultaneous play called Support Play. Two players can play locally or online together in order to explore and battle. Players can also trade. A Nintendo Switch Online subscription is required, however.
- The games will only feature the original 151 Pokémon, plus their respective their Mega Evolutions from Generation VI, their Alola forms from Generation VII, and the new Pokémon Meltan. This makes these games the first in the series where not every Pokémon revealed at the time is programmed into the games.
- Wild Pokémon will appear in the overworld instead of hiding in tall grass. Instead of walking through tall grass, the player character can simply walk up to one of the Pokémon, which will trigger an encounter.
- The starter Pokémon will stay out of their Poké Ball, a game mechanic that was originally exclusive to Pikachu in the original Pokémon Yellow game. Pikachu rides on the player character's shoulder, while Eevee rides on their head. An additional Pokémon can now be chosen to follow the player character, similar to Pokémon HeartGold and SoulSilver.
- CP is still a feature in the game which is calculated with a mix of stats and IVs which gives out the calculated CP and level.
- Wild Pokémon that are caught give EXP. The smaller the Pokémon that is caught (e.g Rattata, Diglett) the less EXP. The larger the Pokémon that is caught (e.g Snorlax, Gyarados) the more EXP.
- The rival is shown to be much friendlier in these games, although he does not appear to be the same character as Blue.
- In order to access certain gyms, one must have at least some kind of Pokémon to go inside (e.g Pewter Gym requires a Grass-type Pokémon or Water-type Pokémon to access it).
- The GO Park replaces the Safari Zone. Pokémon from Pokémon GO can be transported here. The higher the CP of a Pokémon transferred from Pokémon GO, the higher level it will be in the GO Park.
- Candy can be used to boost different stats.
- A new device is released called the Poké Ball Plus. It can be used as a Joy-Con and can keep Pokémon caught in-game inside it, similar to the Pokéwalker. When bought, it will come with a special Mew gift.
- One can ride larger Pokémon.
- Oddish, Sandshrew, and Growlithe will be exclusive to Pokémon Let’s Go Pikachu while Bellsprout, Meowth, and Vulpix will be exclusive to Pokémon Let’s Go Eevee.
- Shiny Pokémon will be catchable in the game, they can be distinguished in the overworld by a small glimmer of "star-like particles" around the Pokémon.
- Mega Evolution, a mechanic introduced in Generation VI, will be present in these games.
- Let's Go Pikachu and Let's Go Eevee are omitting held items and Pokémon abilities from battles.
- New exclusive moves are introduced:
- Instead of PC boxes, the player character carries a Pokémon box that allows them to switch out the Pokémon in their party at will, rather than having to access a PC.
- HM's are replaced by Special Techniques. These are skills that the partner Pokémon can use but do not take up move slots.
- Surf is Sea Skim.
- Cut is Chop Down.
- Fly is Sky Dash.
- A brand new Steel-type Mythical Pokémon, Meltan.
- So far, these titles have the longest names out of all games.
- These are the first remakes of a third version. Previously, every remade game has been a remake of two paired games.
- These are the first core series games since Ruby and Sapphire to not be compatible with previous titles in any way.
- Gyms will return in these games.
- This game works differently from standard games of the main series, as while it's not a spin-off as per the official site listing and it's still a main series game, it's the first time that a generation features main series games from two consoles (in this case, the Nintendo 3DS and the Nintendo Switch). Furthermore, the 2019 VGC rules use Ultra Sun and Ultra Moon rather than the Let's Go games, whereas VGC typically uses the most recent main series game. This is also the first overall game (including when factoring spin-offs) in the franchise to be released on the Switch as well.
- These are the first core series games since Generation III that the Version Mascots are not Legendary Pokémon.
