Pokemon is about the universe it was created in. It was the perfect on the go game when we were children and it even had a great anime to go with it. When you were home, you watched Ash and Pikachu take on the world of pokemon. Everything looked so vibrant and cool. Then when it was time for you to go with your parents to a house party, you could play Pokemon on your Gameboy.
It’s just a nostalgia franchise now, but that’s okay. Most people are unhappy with how Game Freak is handling the role of building these games, but maybe one day they’ll make a turn.
