The only one I can think of is Burnout Paradise (criterion). It was released for both platforms simulatneously. What other games have been there like that?
Updated List:
- Burnout Paradise
- Devil May Cry 4
- Mirror's Edge
- Tekken 6
- Ghostbuster- the Game
- Skate 2
- Dead Space
** EA has stated that all games from now (Feb 2008) on will have PS3 as the lead platform.
