PS3: (unfortunately, my only system this gen) For God of War 3, Metal Gear Solid 4, Uncharted, Motorstorm, and Gran Turismo 5.
I just don't have enough money to purchase all the other consoles this gen. I really wish I did though. My friends are nagging me to get a 360, and I told them that I'd rather focus my spending money on just one system for now to save dough....*sigh*
