A good fighting game, one I had a lot of fun playing.
As far as the story if that's what you want to call it, it's just really short too short for me. That's one thing that I wish was different but it isn't something I'm going to complain about because it didn't take anything away from it for me. And also you get to see the MK and DC characters interact with each other in cut scenes, that is a big plus and something that I thought was really cool to watch.
One thing I've seen a lot of people complain about is how much gore there is, if you played MK before you know there's just so much of it. And it's really cool to see that, but here in this game there isn't much it's really been toned down. Unlike most people it really didn't bother me much, their really ain't no reason to complain about it anyway. But it would have been great if there was just a little bit more in there.
Overall MK vs. DC Universe is a really great game, and one I had a lot of fun with. And to be honest I might have had more fun if I played it before I did Street Fighter IV, but I can't go back in time. If you like fighting games you'll defiantly like this one, don't pass it up.
