Board game enthusiast and NYU Game Center teacher Geoff Engelstein was stunned to find, while trawling the archives of celebrated author Kurt Vonnegut at Indiana University, evidence that in 1956 Vonnegut developed, and spent a year pitching, a board wargame to publishers.
Alongside the letters, Engelstein found an original, complete set of rules for GHQ: General Headquarters, Vonnegut's simple board wargame.
It was never published, but Vonnegut of course went on to incredible fame, particularly for the novel Slaughterhouse-Five. With the permission of the Vonnegut estate, Engelstein went on to tweak GHQ into a publishable state, give it some appropriate graphic design, and get it published after 70 years sitting in obscurity.
It promptly sold out. Now it's back in stock at retailer Barnes & Noble, where you can find a nicely realized edition of GHQ using simple wooden pieces.
It's also accompanied by a 24-page booklet that shows off Vonnegut's design notes so you can get some quite rare insight into his game design process.
