Yeah... No I'm not asking which is better. I'm trying to figure out which titles are exclusives for the individual consoles. I'm not big on sports (I'm just not into sports video games

) and my attention to FPS is meager because I'm a mouse/keyboard kind of guy.
I'm asking because I have a free pass to a game console this Christmas and my choice is between the 360 and PS3 (we have two Wii's already, no sense in getting a third

).
All I've been able to really come up with for the 360 are games like Left 4 Dead and Beautiful Katamari.
For the PS3 all I've come up with is God of War, Little Big Planet and Katamari Forever. GoW and Katamari are a big ones. Coupled with the builtin WiFi, the PS3 might win my choice.
Most of the games I already like exist on both consoles such as GTA, Fallout and games that have my interest like Bioshock, The Orange Box, and Dead Space.
I guess that leaves some exclusive console title I forgot about and the online stores. Am I forgetting some must-have exclusive titles for either console?
