KOTOR, pretty much every Zelda game (I played one for a few minutes and went to play something else), WoW, MW2 for certain reasons, Counter Strike, any Resident Evil besides Umbrella Chronicles and 4 on Wii, any Elder Scrolls game.
Off subject, but since all these people haven't played whatever game, do they have the right to judge it? I know someone I go to college with and he talks shit on all these popular games (Call of Duty 4, Final Fantasy VII, etc), and says all these stupid stereotypes about them, yet has never played them.
