Let's see:
FPS - Halo
TPS - Gears
RPG - Mass Effect, Fable // Lost Odyssey, Blue Dragon, Infinite Undiscovery
Platformer - Banjo Kazooie, Kameo, Viva Pinata
RTS - Halo Wars
Action / Adventure - Splinter Cell Conviction, Ninja Blade (underrated!!!!), Ninety-Nine Nights, Crackdown
So I voted for Action / Adventure, because even though there are some exclusive games that are awesome, there is nothing on the Xbox 360 like a Shenmue or any other truely epic game. And I do love nice storys in videogames and platformer are not that great for telling deep storys.
I think Rare will come up with some nice Platformers though.
Imagine not having GamePass on your console...
