Wallenstein! Wallenstein is also being reprinted as Shogun by Rio Grande Games in a few months.
If you haven't heard of Wallenstein, it's a strategic game covering the Thirty Years' War. It's kind of a war game, like Axis & Allies, and kind of a resource management game, since you have to be able to feed your populace, and also tax your populace without them rebelling, all while trying to conquer more countries. The best part: the rules are simple! No harder to learn than Monopoly or most other popular games. Lots of fun!
