Jason Rohrer, designer of the games Passage, The Castle Doctrine and Diamond Trust of London, designed a game that likely won't be played in his lifetime. Instead, he buried the game, with the intention that it wouldn't be played for the next two thousand years.
Back in March, Rohrer presented A Game for Someone at the 10th Game Design Challenge. Or rather, he gave a presentation about A Game for Someone. Inspired in part by ancient games that are played by modern people, like Mancala, and in part by the architects of grand structures whose completion they don't live to see, Rohrer decided to design a game meant to be played by someone in the distant future.
Since A Game for Someone was meant to never be played by a human during our lifetime, Rohrer used an AI to playtest the rules. He crafted the board and pieces out of titanium, so that it would weather the years. Then he buried the game somewhere in the Nevada desert. During the presentation, each member of the audience received a piece of paper with 900 GPS coordinates listed on it. Rohrer said there were a million coordinates in total, and that if someone were to visit one set of coordinates with a metal detector once a day, the game would be found within 2,700 years.
