Back in 2001, when I was still teaching at the University of Georgia, I designed a political simulation for my upper-division course on the U.S. between the World Wars. Its called "Senate Baron," and its meant to simulate the politics of the U.S. Senate during the 1930s. I tested it in the classroom, and realized it had some problems, which Ive tried to fix in the latest version. Anyway, anyone whos interested can find it here, at the site of the Academic Gaming Review. I wouldnt recommend it for high school classes (except perhaps at the AP level), but I would welcome any comments--particularly from teachers.
