Origins of World War I appears in Sid Sackson's well-known game book A Gamut of Games. Gameplay is very similar to Origins of World War II, which was published by Avalon Hill in 1971, although players have to provide their own game components.
The following description was taken from A Gamut of Games introduction of this game:
A political/strategy game in which five players represent the five major nations in pre-World War I Europe. They must compete against each other to achieve each nation's 'national objectives'. While actual war is not allowed in the game, the play should show quite clearly how tensions developed to such a high pitch in 1914.
