I happened to be looking at the website of Breakaway Games, and among their games I saw Civ III: Conquests, Tropico: Paradise Island, Austerlitz: Napoleon's Greatest Victory, and... A Force More Powerful. From the game's website:
Can a computer game teach how to fight real-world adversaries—dictators, military occupiers and corrupt rulers, using methods that have succeeded in actual conflicts—not with laser rays or AK47s, but with non-military strategies and nonviolent weapons? Such a game, A Force More Powerful (AFMP), is now available. A unique collaboration of experts on nonviolent conflict working with veteran game designers has developed a simulation game that teaches the strategy of nonviolent conflict. A dozen scenarios, inspired by recent history, include conflicts against dictators, occupiers, colonizers and corrupt regimes, as well as struggles to secure the political and human rights of ethnic and racial minorities and women.
How cool - irrespective of how the game plays (I can't try it out), it's cool that games like this are made. Here is an article about the game from Business Week.
