Paths of Glory is vast and complex, and a full game of the Campaign scenario can last more than 8 hours. This is obviously a major time commitment, and for that reason, several alternative campaigns and variants have appeared over the years.
The first official additions appeared in the 2001 Player’s Guide. This expansion and strategy guide introduced new scenarios for the game starting in 1915, 1916, and 1917. It also included 20 new cards to the deck. Additionally, the guide suggested many variants on gameplay, including card ideas, strategic options, pre-war options that alter starting forces, and historical variants.
The game was designed to reflect the events of WWI, but also allowed the course of the war to play out in many different ways. The designer did not want to clutter the game design with the limitations that historical accuracy would bring, as in some preceding war-games published by GMT Games. Some gamers wanted more historical accuracy, to let the game play out in the way that WWI really played. With this in mind, a historical scenario was created by the game’s designer. In the 2010 reprint of the game, the Historical Scenario was officially included in the rules.
Paths of Glory has become a favourite game in tournaments hosted by the Boardgame Players Association (BPA). The game is a regular feature at the BPA’s annual World Boardgaming Championships (WBC). They also organise tournaments where players compete over email. The 2010 edition of the rules contains specific rules for the tournament play. The standard rules limit tournament play to the Limited War or Campaign Scenarios. The BPA often uses the Historical Scenario in their competitions, with minor changes. Additionally, there are rules about the length of rounds, which are limited to 7 hours, and adjudication in case time runs out before a conclusion has been reached.
