Check out A Force More Powerful !
The political simulation has been created by U.S. developer Breakaway Games on behalf of the International Center on Nonviolent Conflict. The strategy game sims Ghandi and the independence movement in post-World War II India, the American civil rights movement of the 1960's, and the struggle against former Serbian dictator Slobodan Milosevic.
A scenario editor allows players to create hypothetical - or even real world - situations and explore nonviolent political solutions. GP is well-acquainted with Maryland-based Breakaway Games, which is led by veteran game designer Doug Whatley. Before getting into the Serious Games movement, Breakaway created GP favorites ABC Monday Night Football and Waterloo: Napoleon's Last Battle.
