standard RPG: depends on how much you enjoy the console style of RPGs... if you do there are a lot, if you don't there are very few... possibly of note: Final Fantasy VII, Lunar: Silver Star Story Complete, Lunar 2: Eternal Blue, Persona 2: Eternal Torment, Xenogears

action-RPG: Tales of Destiny 1/2, Star Ocean: The Second Story, Legend of Mana, DarkStone

strategy: Ogre Battle, Tactics Ogre, Final Fantasy Tactics, Space Hulk: Vengeance of the Blood Angels (FPS/strategy hybrid, fun but very hard...)
