Gore fest? Definitely... Brutal? Definitely..
Not to ding on other fighting games, but some of them are pussy as hell (DoA) and some are too slow (SF). To tie in to anime, I love Blazblu with all my heart, but there aren't many fighters and 2D sprites isn't where it's at. Mortal Kombat, I think, really brings fighting back because no one looks perfect after a brutal match. Yes the story is totally out there, but at the same time, the combat is right where it should be. It's not too fast like Blazblu and it's not too slow like SSF. X-ray moves are easy to execute on the controller, but you have to time them well to hit. Fatalities also give the presence of Astral finishes from Blazblu while still having the epicness of Mortal Kombat's gore factor.
Maybe you aren't young enough to remember playing Mortal Kombat at the arcades and the whole "Kill of the Hill" aspect of winner plays again. I've been in deep freeze since the 3rd game and all I know is the 9th one is Godly.
