Kreate-a-fatality may seem like a very cool feature , but maybe not. You are timed and it's probably hard to get any satasfying results due to the time. I would much rather just have the old fatalities back.
Maybe instead of this feature Midway can just give a character 3 or even 4 fatalities! Or they could still have this kreate-a-fatality feature, but in a different way. There could be a menu that you go to to create a fatality for any given character (maybe there can already be a a default one made). Then you can make up the code you type in to perform it. This may have better results because you are not timed and given the unlimited time you can take doing this you can make almost any fatality imaginable .
These are only my opinions and I am open to others opinions, too.
