MK9 looks better than MKvsDC but the story is lame as hell:
Developer Ed Boon describes the game as an altered re-telling of the events of the original first three Mortal Kombatgames (MK, MK II, and MK3).
...Raiden is about to be killed by Shao Kahn, and just before he delivers the last blow, he [Raiden] sends a mental message to his earlier self, so the camera rewinds back to Mortal Kombat 1. The Raiden from back then gets a message and he doesn't know what's going on, but he knows something bad's going to happen, and the game spans Mortal Kombat 1, 2, and 3, retelling the story with an enlightened Raiden, and he's changing the course of things, so everything you've seen happen before ? Liu Kang winning, the guys turning into cybernetic ninjas, are changed around, so you might see a character become cybernetic who wasn't before, and so you see a different version [of events].
WTF?!
