Digimon World
Bandai · 1999
Digimon World is a PlayStation RPG where raising a single Digimon — through feeding, training, resting, and bathroom use — determines its evolution, intelligence, and battle effectiveness. Poor care locks players into Numemon, a weak Champion form. Battles restore order to File City by recruiting feral Digimon. When the Digimon ages out, it reverts to an egg — forcing a full restart.
