Bayli and Travis only people I know who have a PS3 of their own lulz.
Bottom line: Neither has exclusives the other one should really be envious of.
Killzone = Halo
inFamous = Poor man's Crackdown without the funnies
Gears of War = Uncharted minus the story
God of War = shit, why aren't you playing a good action game?
If you don't have a PC, there are games that are on the Xbox but not PS3 like Mass Effect and Left 4 Dead, but if you have a gaming PC, why would you bother with a console in the first place!? their libraries are practically even with no game standing out as a reason to buy either console.
PS3 = Xbox with bad online
Xbox = PS3 without bluray
my girlfriend got it for me for my birthday.
