I've run this system at several conventions over the last few years with some success (participation games at US conventions). At the very least, the players do grasp the rules and the system works. It follows on my Armies At Lutzen idea of putting the player in the position of army commander. I have not written out the rules yet, but I have a complete set of player reference sheets, event cards, terrain effects, and other supporting references to enable play. I currently have a version for the Thirty Years War (and Eastern Renaissance). I intend to expand into other eras later.
