arguably 2 of the biggest:
FF13
Tekken 6


cant think of anything else atm..those two are what came to mind instantaneously

I'm thinking more, DMC4 & Last Remnant (it was initially a PS3 exclusive).. seems like PS3 normally "steals" FPS exclusives while 360 "steals" JRPGs in most cases

I think it more of the game than the console, I have friend that bought a gamecube just so that he could play The rogue squadron series.

I miss the ace combat series....

been following since PS1 days and now suddenly shocked that Ace Combat 6 is on 360???

so it's a give and take..there ARE xbox360 games that came out on the ps3=)hahah,nv reali gave that fact a thought coz i didnt know.i'm foreseeing more of the 'exclusives' turning non exclusives in the nx couple of months.coz the matter of fact is, every developer is definitely out to make money.why make a game exclusive only on one console if u can double it by producing it on 2 different consoles?rite?=)anyways,the global recession is hitting soon.bet these game companies need all the cash they can get..hahah
