The game now supports league-play, i.e. round-robin tournaments. Each participant will compete against each other competitor exactly once. 2 points will be awarded for victories, 1 point for draws. The player with the most points at the end will win the tournament.
For n players (or teams), each player will have to play n-1 games. For Blitz, all games for a round need to be completed before the next round starts. For Longhaul (8h+/turn), all games are setup at the same time.
Clan or Team-Play (requires team-play map!): players in the same clan will be paired together. Other players and extra clan players are randomly assigned to teams. Please note I haven't fully tested team-play, but I think it should work: please report team-play problems!
