phpDiplomacy

Lately, I've been playing Diplomacy. The site is a PHP implementation of the classic board game. It's still a beta, and not everything works, but it's still quite fun.

Diplomacy is a board game somewhat like Risk (as in, turn-based world-domination). Differences are that there is no chance involved; you only successfully attack if you actually have more forces involved in the battle. Also, the card aspect of the game is not there.

In this implementation, each phase is 24 hours long, allowing you to go and submit your moves whenever is convenient for you. There is also chat functionality, so you can arrange alliances and the like.

Go check it out. My username is Vollmond there.

Fun fact: Diplomacy is the game most played by mail in history, second only to chess.
