It’s a widely-circulated bit of nerd trivia that The Expanse, the popular series of science fiction novels and rather good television show, actually started as a tabletop roleplaying and forum play-by-post setting. Well, now the authors are partnering with publisher Green Ronin to create a proper version of the setting in pen and paper: The Expanse Roleplaying Game. 

The game will use Green Ronin’s AGE system, marking the first time that roleplaying system has been used for sci-fi. It’s currently on a Kickstarter campaign, with hardback books clocking in at $50, and has quite predictably passed its initial funding goal of $30,000. The campaign ends Wednesday, August 22nd.
