Get ready? FIGHT!

Mortal Kombat but only when I started varsity, wasn't allowed to indulge in games much as a child

Mortal Kombat, specifically 1, 2, and 4. It was all the rage. Speaking of which, I do remember playing Primal Rage for a little whike, but nowhere near as much. Also Virtua Fighter, before moving on to Guilty Gear.
