Marvel Vs. Capcom 3 has a nice feature packed into the fighter, it solves the problem of quitters in online play. Some people play games for fun, others play to win, and if they don’t win, they quit. Capcom is implementing a feature that will pair players that quit frequently with other quitters by keeping an invisible stat that only the matchmaking program of the game can see. If you are seen by Capcom’s matchmaking service as a quitter, you will be paired with other players that quit often thus solving the problem for people that just want to have a good time, win or lose.
Leave it to Capcom to fix this problem, which was a very big thorn in the side of Super Street Fighter IV.
