Did you have a choose a different character or random rule. Picrel is a game I played with my first roommate after college. Played the living shit out of it. Always had a rule where you couldn't play the same character twice until you've ran through all the others. So an hour of gameplay was always about saving your favorites for last. For games with random select we would use those to create matchups. Modern fighting is all about having a main character and I think it's got to be terrible for the genre. I understand having a main is emergent with online play, but that makes most people only get into 5% of the game. Idk what were your fighting game rules for heads up play.
