I used to play the crap out of this in the arcades, spending crazy quarters on it! Once it was coming to home systems, I was like it's on!!!! I had both a Genesis & SNES. I chose to get it on Genesis first. Shortly after I got it for the Super too. MK has 7 characters: Scorpion,Liu Kang,Raiden,Sub-Zero,Kano,Johnny Cage & Sonya. Each have signiture/tradmark moves much like Street Fighter 2. And the characters also have their own fatalities, which you do after winning 2 rounds. Both versions (Sega & Nintendo) have pros and cons....Here's SNES'....
