I can afford one game, and one game only.

[M.U.G.E.N]

Unless you ultra suck at QT events get GOW3...the 10hour ride is an epic one and one you will repeat, the scale is unmatched by any game out in history imo

HR: is a unique gaming experience and can be replayed in many ways to get different outcomes, heck if you miss one QT event even that will have a noticeable impact on it, again unless your a gamer who 'really' suck at QT, you will enjoy it

Batman: get it on PS3 cuz you can play as the Joker as well since it's ps3 exclusive, great game btw, very nice gameplay and atmosphere

other games aren't out yet so I can't give you an opinion on them, simple as that. W/e you pick up, hope you have fun :)
