We should eventually be able to set up and find seasons, ladders, and championships for others to join and play in game. I'm imagining how cool it would be to search for a "league" by region, match times, game options, arena, team size, then pick a team (or random player) and join! Matches or 3- or 5-match sets would nominally be scheduled for a specific day at a specific time, e.g., connection must be made within a ~20-minute window. No-shows lose, and the system could have a reliability / merit score to facilitate joining leagues with more reliable people (leagues could set a cutoff). This would be best to implement after friend lists, room-code favorites lists (and remembering the the last room code), I think.
