Playstation All-Stars Instantaneously brings to mind Smash Brothers where in lies its biggest problem, you can't help but to compare the two, and unfortunately this game is no Smash Bros, but putting that aside it is still a fun game!
There is a certain charm about being able to smash sack boy to bits with Kratos's blades, A cheap 4 player fighter that is a good party game to have especially on the PS3. yeah maybe more characters would have been nice, and the DLCs are horribly over-priced. But for the price your paying for it it's definately well worth the purchase.
Not a serious fighter but great if you just wanna have some mates over to Battle Royale
