For me the MK game's were never up to much. The second one wasn't bad , but wasn't a patch on Street Fighter 2 Turbo. I find the MK game's to be very slow and clumsy mainly due to how moves are pulled off. Trying to tap in back, back, forward, punch takes forever compared to down, down forward, forward, punch. As the later all flows together in one continues motion.

The blood and gut's finishing moves never really interested me either. They usually required such a massive amount of key presses to perform and weren't really that impresive.

I'll take Street Fighter or King Of Fighters anyday over an MK game, but thats just my preference.
