Monster Rancher Advance

Monster Rancher returns to its battle-arena roots in its first incarnation on the GBA, Monster Rancher (Farm) Advance. Aroma and Zest are a monster-breeding team in need of help. Build your own team of monsters (unlike previous games in the series, you use alphanumeric characters to generate your monsters) to battle and help train theirs. The more you play, the better the monsters you can create. Now you can let older monsters train younger ones.
