"Numenera" is a Kickstarter-funded table-top RPG created by Cook, set a billion years in the future in a science fantasy and post-apocalyptic setting with streamlined rules that prioritize the story, the action, and the wild ideas. It raised over $500,000 (more than 25 times its goal of $20,000). System playtesting was announced on October 30, 2012, and the game was released on August 14, 2013. Cook has stated that David "Zeb" Cook's (no relation) Planescape fantasy world was a significant influence on concepts in "Numenera".
