Pokémon Pokopia featured 300 Pokémon at launch.
The launch version selected 300 Pokémon from Generations I through IX. This roster supported the game’s habitat-focused design, because different species appear when players create environments matching their needs and preferences.
Pokopia does not use its roster only for battles. Pokémon can teach Ditto moves, help cultivate the landscape, converse with other Pokémon, and settle into habitats designed around their requirements. The selection therefore serves the simulation’s social and environmental systems as much as it serves collection.
The number can be confused with the total number of Pokémon in the wider franchise or with later additions. The 300 figure describes the game at release, while subsequent downloadable content and updates can expand the available roster. It is also not the same as the original 151 Pokémon from Generation I, even though Kanto is the story setting.
