For instance, your Pokémon (or at least your Pikachu or Eevee) will be able to sport a variety of different accessories, adding a level of customization to the games that hasn't been seen before (unless you're into the rigors of EV training, which again, Let's Go isn't about).
As well as the new features coming to the game it's been revealed that players will be able to battle famous gym leaders like Brock and Misty straight from the anime, as well as locking heads with Team Rocket. Whether it's catching Pokemon or training to become the Pokemon League Champion, players can go solo or partner up for local co-op, which should make capturing wild Pokemon a little bit easier.
Pokemon GO fans have been wondering how an Eevee Community Day might work since the monthly events started and it sounds like we're about to find out. Oddish, Sandshrew, and Growlithe have been confirmed to only appear in Let's Go, Pikachu, while Bellsprout, Vulpix, and Meowth will only be available in Let's Go, Eevee. We'll also be able to trade with other people both locally and online. The games are based on the classic Pokemon Yellow version and take place in the Kanto region.
