I buy multi-platform games games on 360 primarily because they often run/look better but also for playing with friends via Live. Exclusives I've enjoyed but far from complete list:

Alan Wake

Gears of War Series

Saints Row

Halo Series

Lost Odyssey

Banjo Kazooie: Nuts & Bolts

Dance Central Series

The Gunstringer

Fable 2

Forza Series

Chrome Hounds

Dead or Alive 4

Culdcept Saga

Earth Defense Force 2017

Crackdown

Deathsmiles II

Operation Darkness

Raiden IV

-------- XBLA ---------

Shadow Complex

Assault Heroes Series

Bomberman Live

Explosion Man Series

Bangaioh HD: Missile Fury

Guardian Heroes

Soulcalibur

Radiant Silvergun

Omega 5

Virtual On: Oratorio Tangram

R-Type: Dimensions

-------- If PC doesn't count --------

Mass Effect Series

Condemned: Criminal Origins

Insanely Twisted Shadow Planet

Bastion

Monday Night Combat

I think Fable 2 is 360 only and definitely the best of the series.

Do you count XBLA and Indie titles? There's literally dozens of those that are worth playing and will probably never be on ps3.

I love Rocket Robot on Wheels!
