This classic game of negotiation has taken many forms over the years.
In the game, players represent one of the seven "Great Powers of Europe" (Great Britain, France, Austria-Hungary, Germany, Italy, Russia or Turkey) in the years prior to the first World War. Play start in the Spring of 1901, and players make both Spring and Autumn moves each year. There are only two types of military units: armies and fleets. On a given turn, each of your military units has limited options: they can move into an adjoining territory, support an allied unit in an attack on an adjoining territory, support an allied unit in defending an adjoining territory, or hold their position. Players will instruct each of their units by writing a set of "orders." The outcome of every turn is determined by the rules of the game. There are no dice rolls or other elements of chance. With its incredibly simplistic movement mechanics combined with a significant negotiation element, this system is highly respected by many gamers.
