There is a "forum for forum games" that is going to be running one set during the Cold War. 50 users have signed up so far. It will start on October 1. Here is a summary:
Balance of Power XIII begins in January 1981. Players assume the role of countries, militant groups, political parties, or whatever other position they can think of. Every year is divided into Early (January - April), Mid (May - August) and Late (September - December) periods. Each turn lasts about four days in the real world.
The game is played by sending a private message to the Game Master (the person in charge of the game) with information on what actions you want to do for the turn. The GM will inform you how much an action costs in terms of credits or points, as well as their chance of success (from 1 to 10) and potential effects. Turn PMs may be formatted however one wishes, so long as it's legible to the GM.

The concept is loosely based off of a PC game from the 1980's of the same name.
