About the game

In May 1618, two imperial regents of the Habsburg Empire, along with their secretary, were thrown from the window of the council room in Prague Castle for violating an agreement that protected Protestant religious rights. The act, known as the Defenestration of Prague, marked the beginning of 30 bloody years of warfare—the Thirty Years War. Cuius Regio explores the operational military aspects of this pivotal period in European history and focuses on the maneuvers and battles that shook Europe for three decades. The game includes scenarios covering the Bohemian Revolt, the Danish intervention, the Swedish intervention, the French intervention, and a Thirty Years War campaign of 31 turns lasting from 1618 to 1648. Each scenario has a unique character, and the game can be played in as little as an hour and a half (for a short scenario) or can be a multi-session game for the full campaign. Each turn has a variable duration that depends on the number of armies on the map and how those armies are employed. Armies can conduct operations several times in a turn but the more they do, the less effective they become. Combat is an integrated system for field battles and sieges and is resolved by a die roll, modified by each army's leadership, composition, and condition, on a simple Battle Results Table. —description from the publisher
