Savage Worlds
Savage Worlds is a generic role playing rules system designed to work in any setting. Described as "Fast, furious, and fun!" the system is geared towards a pulp adventure feel.
Savage Worlds was originally published by Pinnacle Entertainment in 2003, but it is a simplified ruleset based on the one originally developed for Deadlands in the 1990s. It has subsequently had numerous editions and branched out into dozens of different settings.
