I've done some easy 16-p single-elim brackets, but I've always wanted to go to the ultimate limit -- the 5-game tourney like the one that qwert did here: http://www.conquerclub.com/forum/viewtopic.php?t=138620.
Two 8-player standard games. Winners of the two games will face off in a best-of-3 1v1 playoff to determine the winner. Map is of course Random, and all settings are default (automatic sequential escalating chained sunny no trench).
If I didn't have the "street cred" of over 100 tourneys on the Organizers Hall of Fame, I wouldn't dare do this, but I figure I'm due...

This is my 120th tournament!
