My cousin let me play his friend's SNES copy of Mortal Kombat a few times, but I never really got into it. I wasn't very good, considering I was really young and didn't play fighting games much.
My uncle got me a copy of Ultimate Mortal Kombat 3 for the Playstation when I was about 10. I highly doubt he knew what he got me. I couldn't do fatalities, still couldn't play well, and disliked the "Bottom of the Pit" stage. All that said, I really didn't play violent games much as a kid. I played Gundam: Battle Assault 2 and Final Fantasy 8. My first games were Mario, Sonic, and Duck Hunt.
