In 1956, not-yet-famous author Kurt Vonnegut unsuccessfully attempted to publish a board game. That game, GHQ, was then stored in a box for decades until designer Geoff Engelstein read about it in a biography and began the long process of restoring this historical artifact. On today's Space-Cast!, we sit down with Geoff to discuss how GHQ traveled across time, its surprising innovations, and what it might say about Vonnegut's efforts to contextualize his wartime experiences.
