Dude, I can totally get you The Liberation of Sisyphus: Mars 244 if you want to run it. The main thing it lacks at this point is a detailed instruction book, but you probably don’t need that having run/played this type of game before. (Though by October, I could also have something more officially written up.) Having another GMless/GMful game on hand for cons is part of the motivation behind this, because I can enjoy running more stuff if I also get to play. Lemme know if you’re interested.
