Teach Macro-Economics with Excel

When I was first learning how to program a computer (a TI-994A with Extended Basic!), a high school teacher asked me to attempt to program a macro-economic simulator that could be used in the classroom to teach economics.

I thought this was a pretty cool site - Francisco Blasques is doing the same thing, with three games in Excel. Your goal is to reach a GDP of 200 in 90 turns or less! If you are a teacher trying to teach economics, or merely want to relive the days of high school econ, check out these simulations from Francisco. The descriptions are here, and the downloads are here.
