Recreating the turbulent era of the Reformation, from the viewpoint of political/religious interaction and military activity. A Mighty Fortress is designed with a mechanical simplicity that is matched only by the subtlety of the game's interplay among contesting forces.

A Mighty Fortress simulates the conditions, which made possible the spread of the Lutheran Reformation and the subsequent Catholic reaction (the Counter-Reformation) in the years 1532-1555. The game recreates the actual historical objectives of the major countries in Europe in the Sixteenth Century as well as their military strengths and resources. There are six players in the game representing the six major countries, England, France, the Ottoman Empire, the Hapsburgs, the Pope, and the collection of German states we will call The Lutherans.

A Mighty Fortress covers the twenty-four years from 1532 to 1555 -- a period fraught with shifting alliances, political and religious fervor, and frantic efforts to shift the balance of power. Theological debates, treaties of peace, declarations of war, excommunication, taxation, and missionaries -- all are included in this simulation of one of the most violent and implacably hostile eras of European history. The game covers all actions from the year 1532 -- right after formation of the Schmalkaldic League -- until 1555 and the Peace of Augsburg, which guaranteed Lutheranism as a religion and allowed the German estates to choose between that and Catholicism.
