I'm not in the Madden one but did a NBA2k one awhile back and it was pretty easy to get games set up. Everyone had 1 week to work it out with their opponent, obviously the GM would need to monitor who's fault it was if a match didn't happen and punish that person however we decide to punish them (work a program with Big Show).
if we do something with a guest ref, etc ... can all 3 people get in on the game to play it together? I'm assuming that's possible.
Also, for one on one matches ... are we going to have video? I would love if the matches could be taped and put on Youtube for the league to watch if they wanted.
on that note ...for like a royal rumble scenerio - we can't get everybody on there at once, right? What's the LIMIT of people playing one XBL match online?
