This this Gen is over, let's remissness about Box Art.
Some personal favorites Halo Reach, Halo 3 have always enjoyed the halo box art especially Halo 2's but the was last gen. Red Dead's bad ass John Marston ready to blow you away, with terrible shooting mechanics. Left 4 Dead's, a fucking hand with 4 fingers how badass is that. Dead Rising 1's, a dude with a TV against a ton of zombies.
How About you list you favorite video game box?
