In Pokemon GO, you can take with you an associated Pokémon and walk with it, but if we return to its origin, we get to Yellow Pokémon. In Pokémon: Let's Go, Pikachu! and Pokémon: Let's Go, Eevee! We wanted to expand this feature even more. Pikachu always follows Ash in the anime, while Eevee has become very popular because it can evolve in many different ways. And as I mentioned before , we want this to be the game that people go to play after Pokémon GO, since Pokémon Pokémon Red, Blue, Green and Yellow appear in Pokémon GO, so it seemed like a good decision. Based on these things, we decided that Yellow Pokémon would be the perfect choice.
