Currently, we have "random game" tournaments. The creator of the tournaments selects one or more games, and for each game between participants, a game will be randomly picked from the selected games.
I'd like to propose a variant. Instead of randomly pick a game, a match consisting of all selected games is played. For instance, one may create a "monster tournament" with "Reversi", "Reversi 6x6", "Reversi 10x10" and "Anti Reversi" as the games. All players in the same section would play 4 games against each other - all the reversi variants. You'd score 0 - 4 points (so, if it's a five player section, you could score up to 20 points). All games would start at once (otherwise, tournaments would never get finished).
Just don't sign up for a 20 player/section, 125 game "monster tournament", unless you can handle 2375 new games. ;-)
