Bizarro Diplomacy (rb04)
by Lew Pulsipher
All players are anonymous, and all diplomatic messages are sent through the GM, who includes them with his next adjudication. There is one chance in six per message that it will be randomly misrouted to someone other than the sender and intended recipient. Players must not be permitted to discover the names/addresses of other players, or the game will be ruined.
Players may send messages pretending they went awry--send the message in an envelope with the recipient listed on it, have the GM throw away the envelope (there may even be another inside it) and forward it. But the sender must always truthfully identify himself in each message.
