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 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 the appearance of Pikachu or Eevee, as well as the player character. 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.
- 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.
- Wild Pokémon will appear in the overworld instead of hiding in tall grass. Instead of walking through tall grass, the player 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's shoulder, while Eevee rides on their head. An additional Pokémon can now be chosen to follow the player, 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.
- Pokémon can have a visible aura around them in the overworld that tells their size:
- Red = Bigger than normal
- No aura = Normal
- Blue = Smaller than normal
- The rival is shown to be much friendlier in these games, although it is currently unclear whether he is intended to be the same character as Blue.
- In order to access certain gyms, you 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 exists in the game and 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.
- A Pokémon's stats now show Special Attack and Special Defense rather than only Special.
- 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.
- Eevee is given a gender difference, making it the first Pokémon from an earlier generation to receive a gender difference in a newer one since Generation IV, where gender differences were introduced.
- 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. A trailer released on August 18th, revealed two new Mega Evolutions for Kangaskhan and Gyarados.
- Let's Go Pikachu and Let's Go Eevee are omitting held items and Pokémon abilities from battles.
- New exclusive moves are introduced:
- HM's are renamed and are now called Special Techniques.
- Surf is now Sea Skim.
- Cut is now Chop Down.
- Fly is now Sky Dash.
- 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.
- Gyms will return in these games.
- These are the first main series titles to be released for a home console.
- This is the first instance of a main series title being released on a different system than other titles from the same generation.
