CRESCENT B/X is a minimalist micro-RPG for going on odd, whimsical adventures. To play, you and your friends embody characters in a world of your making—either by using a role-playing setting book, lifting from your favorite book or series, or creating a new world altogether. The game encourages you to focus on worldbuilding rather than rules. By establishing an overall tone for the story that you want to stick to, you can easily make calls during the game for what happens next in the story by deciding on whatever makes the most sense or is the most exciting.
