The game revolves around a young boy (the player can name the protagonist in the beginning of the game), the protagonist, who is drawn into the Digital World through his V-Pet device. Jijimon greets and asks him a few questions, the answers to which determine whether he begins with an Agumon or Gabumon. His goal is to travel around File Island, locating all of the resident Digimon of File City who have turned feral and bring them back, raising Digimon partners in the process. He must train his Digimon and battle his way through all of Digimon World until the once sparsely populated city is flourishing with different Digimon from all of Digimon World. He must eventually go to Infinity Mountain (the final location) to confront the antagonist, Analogman, and the mega Machinedramon, and save the Digital World from destruction.
