From publisher blurb: Spacer8s is a system enhancement for use with the Crazy 8s Rules-Lite Universal Game Engine. This sourcebook is intended to provide supplemental rules material to allow Talespinners to craft stories involving interstellar sci-fi adventures. As the Crazy 8s Rules-Lite Universal Game Engine is designed to be a rules-lite RPG experience that can be easily learned, Spacer8s seeks to introduce useful material to craft stories involving space battles and alien races without bogging the game down with numerous, complicated rules. Spacer8s introduces new alien races and information on interstellar travel designed to be added to any existing Crazy 8s game. These rules are fully compatible with Cyber8s, Fantasy8s, Psychic8s, Super8s and Magic8s.
