And the award for the worst MK game in history goes to....(drumbeat of shame):
MKA - this is the game that turned me off of MK for 4 years, MK9 brought me back. I actually met with several Midway reps at GDC 2008 and told them that to their face, the guy just laughed.
Second worst MK game is MK vs. DC. This is the only MK game I don't actually own. I rented it, played it for about 2 days and never had any desire to play it again. Mediocre graphics, rudimentary gameplay, silly storymode, and, come on, Batman and Superman do not belong in the MK universe.
Third worst is MK4 - this was actually not That bad, except for the graphics and animations. Man, it still boggles my mind how graphics in a game can be that bad. That game definitely looked ugly, although it did have some great aspects. Great story, great new MK characters (Shinnok, Quan Chi, and Reiko), great intro movie, badass FMV endings, not a bad gameplay, even though it was totally lame you lost your weapon if you got hit one time.
The rest of the games were all good.
