Diplomacy

A wonderful/horrific board game that bears a passing similarity to Risk, but without the dice or cards. Developed by Alan B. Callahamer, the game takes place on the eve of WWI, and seven players assume the roles of the seven Great Powers as war breaks out over Europe. Unlike most board games, turns are played simultaneously, with each player writing down his moves for the GM to read. This can lead to lots of "fun" as promises are broken, and players turn on each other.
