Internet Diplomacy

Internet Diplomacy refers to any of a number of online implementations of Diplomacy, a board game in which seven players, each controlling one of the major European powers of the early 20th century, fight for control over Europe.

Instead of communicating face-to-face, as in the board games, or by mail, as in the play-by-mail games, communication and order submission is done over the internet. Typically orders are processed by software, but in the earlier systems a person called a GameMaster would process the orders manually.
