Digimon World 3

Digimon World 3 is a role-playing game developed by Bandai for the PlayStation. You play a kid named Junior who enters an online MMORPG called "Digimon Online", run by the company "MAGAMI". A terrorist attack on the Internet traps Junior and his friends in the game, and he sets out with his Digimon partners to stop them. Unlike previous Digimon World games, the battles against wild Digimon are random and the battle system, although turn-based, is quite different from Digimon World 2. The main difference is that the battles are one on one and not three on three, although you can use another Digimon.
