I want one where people can upload their matches.
Be cool do see if fellow forum members talk the talk, and it's also a cool and easy way to show personal tourneys or matches between friends.
Even better would be the option to also go into a recorded training mode, up to 3 minutes in length, anything you do will be recorded and can be either viewed or uploaded directly to youtube. This would allow anyone to post their combos and tech.
Really, these should be standards by now, we have all the tech to make this happen.
