Monster Rancher 4

Your goal is to raise monsters to win in-game tournaments, explore for items, and improve your ranch. You can also test your raising skills by battling your monsters against a friend in 2P mode.

The game still uses the innovative system of having a player insert music CDs, game discs, or DVDs into the PlayStation 2 to be read and used in making monsters. If you have a good sized collection of music, games, or movies, you can have access to a large variety of monsters very fast.

Monsters can also be made by finding in-game items, and through combining your retired monsters, so having a large collection of discs is not necessary. The game features some cute monsters, some scary/gory types, and enough variety to keep almost anyone busy for a long time.
