For many years faculty have used a variety of games (loosely speaking) as a way to teach their subject. In political science simulations have been common, for example.
Sunday's New York Times discussed the development of several recent video games with a political edge:
Peacemaker, which focuses on the Israeli-Palestinian conflict (check out the video overview here)
And A Force More Powerful, which deals with non-violent political protest.
Whatever the limitations of these games (in technology, design or content), they are intriguing.
