@geofram:
Yeah, I was being unclear.
I play diplomacy on here, on dipbounced, on playdiplomacy and I play the old time actual boardgame. Each has it's strong points, and the main weak one here is the CD thing IMNSHO.
I find that for this particular issue dipbounced's solution is the best: you have rankings for skill, you have rankings for commitment (people delivering orders on time), tyou have a grace period that cover unfortunate circumstances, and when someone goes over grace, the game is paused and players are replaces. Not automatically though, people have to ask to join, and they have to have enough commitment and skill ranking to qualify.
And you can of course have games that actually allow players to go NMR. It's very flexible.
However, it does require that every game has a game master who does not actually play in the game themselves. Which is managed on a voluntary basis, and works fine.
But hey, I'm just an idiot. Do check it out for yourselves.
