MK2 is hella broke. THink of it more like MK3 without a run button and better combo system. It made a big diffrence for me to play someone else who knew what they where doing to make this game fun. Yes I had fun with the demo.
After toying with it for several hours personaly, its easy for me to say that this game is a fairly deep fighting game. I encourage people to give it a chance and wait for the release of the full game, then you can play online against other people (which we have no idea will be god r not currently). Its like MK3 in the sense, its easy to pick up but difficult to master catogory.
Also, pro tip guys, Combo Breakers are the fucking shit in this game.
