Those would definitely be some of the better PC/Xbox games. There are a lot though. Off the top of my head I know there was a Thief game that made it to Xbox, Cthulhu, Stubbs, Arx Fatalis, Deus Ex, KOTOR, Morrowind etc...
Of course...playing Morrowind on Xbox is beneath playing Wonder Momo for 10 straight hours in terms of things I'd want to do.
