A series of games, published between 1976 and 1977, from SPI primarily simulating conflict in the political arena, but also including the military dimension. Designed by by Jim Dunnigan, with an assist from Rudolph W Heinze and Irad Hardy. Redmond Simonsen did the associated iconic art with the series.
Topics covered the Russian Civil War (the "flagship" and first series game), the Reformation and Counter Reformation, the plot(s) to assassinate Hitler, espionage in the 30s and two hypothetical situations: a modern Canadian Civil War and a post apocalyptic landscape.
The games first appeared in Strategy & Tactics as magazine games and then a "designer edition" was issued with mounted maps.
Chicago, Chicago! and Up Against the Wall, Mother****er! , Origins of World War I and II also by Dunnigan, were precursors to the series. Fans of the series have also pointed to Empires of the Middle Ages, The Sword and the Stars and Outreach: The Conquest of the Galaxy, 3000AD, Republic of Rome being similar to these designers.
The series did influence a number of popular wargames that incorporate a healthy political component including Days of Decision/World in Flames, Empires in Arms, Triumph of Chaos, The Persian Gulf among others, the C.O.I.N series (GMT Games) and a number of Avalon Hill titles (Kingmaker, Machiavelli, Republic of Rome and Samurai).
The series can possibly trace lineage to one of the hobby's great games: Diplomacy.
