From the introduction: The game is played in a world where many fantastic animals are able to be energized and stored nicely in a machine called a Poké Ball. These animals are called “pocket monsters,” or Pokémon for short, and they are carried as tools, friends and partners by Pokémon Trainers. Trainers have various skills and abilities each defined by a Trainer’s goal. User summary: This Player's Handbook enumerates Pokémon for "Black/White" emulation play, though as the baseline game it is not branded to a specific release.
