Leader of the French Situationists and writer of books like 'Society of the Spectacle', Debord also spent years developing a strategy game, a few sets of which were produced in 1978. His chess-like game was inspired, not by radical Marxist politics, but by 19th century warfare, Von Clausewitz' theories and Napoleon's campaigns.
This Kriegspiel, or war game, brings into play the operations of two armies of equal strength, each seeking, through manoeuvre and battle, the destruction of its adversary. Each is at the same time obliged to protect, within the territory it occupies, the resources needed for effective campaigning, and to keep its lines of communication open.
