Idk, dayZ was great but it's a mod. Mw3 was an enormous pile of shit, didn't like the last KH or FF, maybe Sleeping Dogs? Do games that haven't come out yet count? Halo4, AC3, and blops 2 (for the zombabies) all look allright. Borderlands 2 was ****ing great but slightly overrated.
The replay value was probably terrible, but since it's the only game from this year I played, DBZ Ultimate Tenkaichi. You could make your own character, and he could go super sayian. That's awesome.
