Never played it, so can't talk about gameplay. Watched all the footage on youtube, just didn't like the look of it. Characters didn't fit, too cartoon'ish & soft. The only comic character's I would've enjoyed playing as woulda been Batman & the Joker. But in my opinion, they shoulda made those 2 more like they were in the latest movie. Whatever.
IMO: Super Man. Does. Not. Belong. Anywhere. Near. MK (unless he's making a cameo appearance where Sub Zero puts some criptonite a tube-sock and beats him to death with it as a fatality)
Wouldn't mind seeing comic characters like Spawn, Slaine & Rorschach in MK. But. I'm better off taking a dump in one hand, and wishing in the other, coz' it's not gonna happen. Whatever. They can make up with it, for me, by putting Jason in MK with Freddy. Again. Wont happen.
