Digimon Adventure: Cathode Tamer

The story of this game is identical to that of "Anode Tamer", and gameplay mechanics are exactly the same: you descend into dungeons to fight monsters in turn-based style, capture the monsters after the battles and then send them to fight new ones. The difference between the two games are the monsters themselves: "Cathode Tamers" features a brand new set of monsters, and since the beginning of the game you encounter different foes. The full collection of monsters can be achieved only if you complete both games.
