AOV Franco-Prussian War 1870 - 71, Imperial Period is an independent Age of Valor (AOV) expansion chapter or mini-module for Age of Eagles II, also known as Napoleonic Fire & Fury. It covers the part of the war between the French Imperial Government of Napoleon III and the North and South German Confederations, up to and including the French surrender at Sedan. As such AOE II is needed to properly play this game. In most cases all rules changes have been imbedded in the Data Charts as well as the charts and tables on the Quick Reference Sheet. All players need to do is use these new specifications or DRMs with the original rules, then play as normal. Any changes unique to the Imperial phase of the Franco-Prussian War, the subject of this expansion set, are included for both the conflict overall, and the included battles of Saarbrucken und Forbach, and Borny et Columbey scenarios. The AOV product line is sold primarily via a digital PDF distribution format, though a hardcopy version is available from certain retailers. It is 28 pages long. —description from the designer
