if you play a lot of games, you should go for 360.
But if you're the person who only plays specific games such as Kingdom of Hearts III, Final Fantasy(is Final fantasy still devoted to PS?), and other console specific games for PS3, u shud get PS3
I'm not sure but im hearing that Assassin's Creed is a really good one that's coming out for PS3.
However, if you're a major gamer and buy lots of games, u shud get 360.
They also have the best online gaming experience thus far out of all the three consoles
