The DC comic characters involved really swayed me into buying this game, my only other experience playing a mortal kombat game was Mortal Kombat Deception(which was brilliant).
I enjoyed the story mode, even though it was a bit short, the fighting is the same as previous MK games, but the brilliant thing about this game is how they intergrate both universes(Mortal and DC). You can smash your way through with Green Lantern or power your way through with superman using either special moves or normal moves(which feel awesome), so the combats good in that respect. But I prefer Tekken as its far more faster and doesn't seem so stiff, I am planning on selling this game now as I've pretty much finished the game and I will buy Tekken. If you're a Mortal Kombat fan I think you'll love it but if you're not then not so. I gave it a 3 as I'm a DC fan.
