I played many RPGs, I'll just list here the ones I really liked.
Arena, Daggerfall, Wizard and Warriors, Diablo, Final Fantasy (the very first one on Nintendo), Zelda (event if some think it's and adventure), Eye of the beholder serie, Dungeon Master (Atari), Ultima VI (that's the only one I played) and a few other ones that I forgot.
