This is an excellent browser version of the classic strategy game. Want to see friendships destroyed? Gather your buddies for a game of Diplomacy.
If you've never played, I'd highly recommend, and it's free.
For those who have played before (online or off), or if you think you can pick it up pretty easily, I've got a game set up. Sign up (again, free), search by game number for 57014. Password is chicken.
