This story may qualify as non-genre as it's a do-it-yourself role-playing-game (RPG) where you read a short episode and then need to make a choice that will lead you to other episodes. As the story is based on a well known science fiction work it has been provisionally included in ISFDB.
This book is an Ace original edition, and has never been previously published.
