I don't recall if this has been brought up or not before, but I shall mention it anyway.
There is a game that can be played via email called "Diplomacy," and since the boards have been quite active with this topic, I was wondering if anyone was interested in trying the game out.
Here are some links:
Good Diplomacy Page
Some Diplomacy Maps
If anyone wants to take a gander at the rules let me know and I can email them to you.
There are opening for 7 countries in the standard version. I haven't looked at the "varients."
