This would be fun, although I'm sure it would remind me of the time that I tried to run a Mario Kart DS tournament. Several people had to drop out because of connection issues. The finals match was a miracle in that all 4 people managed to connect.We should do a GAF tourney sometime in the near future. We need some 90s rap east vs west conflict.
Speaking of tournament mode, it'd be nice to have some other functionality there as well. Particularly, an optional round-robin mode. This would help establish seeding when it's not known. Sure, I can do it manually (and plan to when I host a work tournament), but it would be nice to have it done automatically.
