Suggestion: A Vacation mode
Basically, my idea is to have a vacation mode that one can enable which will automatically skip your turn in any games you're playing, so the other players don't have to wait an extra 72 hours for you to deadbeat out of the game. You'd still be eliminated after three rounds, but this way it's a bit more courteous to other players.
I could see people abusing this by enabling it to get their armies multiplied faster, so I think it would only work if deadbeats didn't get extra armies.
