From the release:
Cyber8s is a cyberpunk setting for use with the Crazy 8s Rules-Lite Universal Game Engine. This sourcebook is intended to provide setting material and supplemental rules to allow Talespinners to craft stories in a futuristic, dystopian cyberpunk world.
As the Crazy 8s Rules-Lite Universal Game Engine is designed to be a rules-lite RPG experience that can be easily learned, Cyber8s seeks to introduce useful material to craft cyberpunk stories without bogging the game down with numerous, complicated rules.
The Cyber8s Tech Manual is released under the Open Game License, allowing anyone to use this game engine as a jumping off point for creating their own worlds and game settings.
