Starbound

User summary: Starbound is a substantive supplement for the Valence 592 (Valence 1st Edition) game. It includes optional rules for traveling, living, and fighting in space, but primarily consists of background information to use in establishing the setting. Starbound could be used with the Valence 2nd Edition rules with some (minimal) revision. The document was published as HTML and as a compiled PDF prior to the commercial release of the rules. From the introduction: 1. Space is big. 2. Space is empty. 3. You have mass. 4. That way is up.
