Live System
A streamlined tabletop roleplaying system based on the Open Gaming framework. It uses a more free-flowing structure, removes character levels, and reduces unnecessary complexity for faster play. The rules support both cinematic adventures and harsher settings such as hard science fiction or gritty modern-day stories. With some conversion, it can also be used to run games based on third-edition and 3.5-era rules.
