Background:
Monster Rancher 2 continues the virtual monster breeding tradition started by the original. With this Playstation title, you can actually use CDs you have, be they music, PC software, or even other game CDs, to spawn unique monsters. Nurture and raise your new critter (or friend) to become the ultimate fighting machine. You may also import your Monster Rancher 1 monsters into this sequel.
