GURPS

GURPS is an acronym for Generic Universal Roleplaying System, a system of rules that govern most modern RPGs. Basic stats like Strength, Dexterity, Health, and Intelligence are the basis of GURPS. Originally to be the engine for Fallout, but eventually dropped when they lost the license. Interplay quickly developed a replacement system, heavily inspired by GURPS, called SPECIAL.
