Final Fantasy games (3), Grand Turismo games (3), Guitar Hero (2), ICO, Shadow of the Colossus, Okami, Tekken series (3), Devil May Cry series (3), Time Crisis (2), Armored Core series (8), Twisted Metal, Soul Calibur 3, Star Ocean, God of War (2), and I'm just going to stop the list here I just pulled these off the top of my head I'm sure theres more.
Grand Turismo? As if one racing game was any different from another.
Guitar Hero is on the 360 now.
ICO, Shadow of the Colussus, and Okami are PS2 exlusives. I doubt that will see sequels on the PS3. The companies who made them may make new exlusives however.
Tekken? That's a joke, right?
Soul Calibur is on the 360.
Twisted Metal still exists?
That reduces your list to: Final Fantasy, Devil May Cry, Time Crises, Armored Core, Star Ocean, and God of War. I'd like to add Metal Gear Solid.
