Twilight of Divine Right: From Defenestration to Restoration is a version of the Twilight of the Sun King: Birth of the Age of Reason rules targeted at refighting large battles from the period 1618 to 1660. The rules feature scenarios for the battles of Fleurus, 1622 and Cheriton, 1644. All measurements in the game are based on a scale choosen by the players, the base width. Movement distances, weapon ranges, etc, are then multiples of whatever base width has been chosen. The base width is half of the frontage of whatever you wish to use as a unit. Therefore any size of figure and also any basing scheme can be used with the rules. Units represent between 1000 and 2000 infantry or 500 to 800 cavalry, depending on the type of unit. Battles can be fought to a conclusion in a reasonable amount of time, most in around 4 hours. Most battles are suitable for a single player a side if you wish. Using a unit frontage of 80 to 120mm means most battles are played on a table 120 to 180cm wide (4 to 6'). The system is simple and innovative. It concentrates on you being a high level commander and bringing out the characteristics of the various troop types. —description from the publisher
