With brawl the players could set up everything, with freedom. But we learned that some folks team up or play differently, making it difficult for all to enjoy. There is a reporting system. As far as technical connection issues, we're still working on it. They use async communication in Mario Kart and other games to improve this, but that doesn't work well for fighting games. So there is cascading failure, especially for four players. That is why they ask people to have the best communication system available (eg a LAN adapter)
