In that vid, he boasts about how great it is that this Mortal Kombat is fast. That's the only thing I actually didn't like about the recent instalments. Twas like you had a video on 2x speed, and your characters moved like robots. All I want in a fighting game is flow, not speed. Fortunately, in the gameplay I am seeing here, I see flow rather than speed, so hopefully this is the case in the finished product.
Its interesting that the early MK games are important here. Hopefully that means the shitty characters of the recent instalments don't exist, and shall never be spoken of again.
