Actually I did get some time with this at Eurogamer Expo. I'm in no way a "pro" at fighters but the things I noticed
1) The stiffness in the controls from Mortal Kombat 9 and Injustice feels gone.
2) Graphics are so good. The game is educational with its detail of the human anatomy.
3) The character varients really do make a difference. You cant jump in from MK9 and into this and expect to succeed. Hell special moves really aren't shared between styles. Its like you want to freeze a guy? pick this style. You want to throw your ice clone? pick this style.
4) Game got a lot of laughs for how "wrong" it is.
Overall I'm a Mortal Kombat whore. I was kinda worried because of the "new" and how Mortal Kombat doesn't do "new" too well, I'm not any more. This, I'm pretty sure, will be a premier fighting game.
Watch as they fuck it up and include fucking Jarek.
