New updatet list:
Left 4 Dead (damn you Valve)
Portal 2 (damn you Valve)
Halo3 (fat chance)
Mass Effects (hopefully soon)
Bioshock (not anymore)
Yup that's about it. 360 owners can keep curbstomping Gears and single-player MMORPG Fable2. But the games above may force me into renting or buying a used 360 sometimes.
