Call it "Anakin's Rule" in honor of the player Anakin who minimized his game after he lost all of his planets and fleet, forcing the winning team to spend extra time mopping up the map after his last teammate had disconnected. (Game started on Friday, July 10, around 6 pm U.S. EST.) So, I propose the creation of a new victory condition for online multiplayer:
If the only people left connected to the game on one of the teams have no planets left and if they either have no colonizer ships left or fewer than, say 200 fleet supply worth of ships left then the other team wins the game and the Victory screen pops up.
