From the introduction: Pokémon Tabletop United is designed to handle a variety of different ideas for Pokémon tabletop RPG campaigns. You can use the system for a traditional game where the players take the role of young Trainers receiving their first Pokémon from a Professor as they prepare to leave town for the first time and conquer the Pokémon League. Or you could play a campaign about Pokémon in Space or a Wild West frontier exploration game.
