No particular order, and I know that's six, not five. I couldn't decide whether to round out the top five with Dead Space or Red Faction, since I really only play RF for multi and Dead Space is sp. Hard to compare the two.

I'm a new arrival to the 360 but so far its:

GTA IV

Prototype

Mass Effect

UFC Undisputed

Eps from LC

1. BioShock
2. Fable II
3. Devil May Cry 4
4. Gears of War 2
5. Assassin's Creed

I'm currently playing Dragon Age and based off the game so far, that will probably work its way up in there. Also waiting for my copy of Assassin's Creed II to arrive at my house so that may also grab a spot once I've finished it.

MW2

Wolfenstein

Fable 2

RE5

Kameo

1. Fable 2
2. Forza 3
3. Left 4 Dead 2
4. Halo 3
