Monster Rancher

Monster Rancher is a console game released in 1997 for the PlayStation system. It is the first game in Tecmo's Monster Rancher series, featuring the raising, fighting, and breeding of monsters.

Although it is possible to acquire a monster in-game, the series is known for the ability to acquire new monsters using Compact Discs (CDs). Players can use any readable CD, and the game creates a monster using the data stored on it.
