Well, I don't play FPS games, but there are only 5 CRPGs that I have no major complaints about: Fallout 1, Planescape: Torment, Baldur's Gate 1 (with ToTSC), Baldur's gate 2 (without ToB), and Ultima 4.
KotOR series is just way to simple. I think that if the publishers/developers actually think that the casual gamer needs that level of simplicity to play the game then they are really insulting the intelligence of the casual gamer.
