Two-players RPG's for playstation?

I own a PS1, PS2, AND PS3 so no worries about which console this is for. I own Elemental Gearbolt (PS1), Gauntlet: Dark Legacy and Gauntlet: Seven Sorrows (PS2), and Untold Legends: Dark Kingom for PS3. Can anyone think of any more? My girlfriend and I need something to play.
