IMO: No game so far defines the PS3. I have discounted MGS 4 even though many PS3 owners highly rate this game because I do not like stealth games and the complex story of the MGS series is confusing. Too many cut scenes in MGS 4 is also a problem with the game. GTA IV and UnCharted are good games but do not define PS3.
Future PS3 games: FF XIII and GT 5. These games could define PS3 and push the limits of the system and be huge software sellers over 5 million copies each.
Honourable future PS3 mentions goes to Kill Zone 2 and God of War 3 both could be promising titles on PS3 which may define PS3.
