I think the problem was, Mortal Kombat was a crappy slopped together game that was ignored, repeated attack animation for EVERYONE and looked like Pit Fighter.
It was only popular when not only could you beat someone you could do the good old unsportsman like nayh nayh move of tearing off a head. Sorry Mk...that childish bit only lasts so long.
Other series don't have to have one stupid gimmick to save a other wish horrible fighting game. Maybe if you made the game better...and make the console AI not super charged like it thinks we are feeding it quarters when it pwns people on easy.
But then again, I thought the story was as clever as a dead retarded slug... best to let it die, or revamp the entire game than pollute a game that was fun, well animated and oh yeah... didn't need to add nut kicks to rub someones face in a loss.
