Hero Games'
Hero System was the first universal roleplaying system, predating GURPS by several years. Characters are designed with points spent on characteristics, skills, and powers, and gotten from disadvantages. Powers are generic and effect-based -- combinations of advantages and limitations are meant to produce any conceivable
playable effect. The Hero System began with its most popular member, the super-hero game
Champions, but also includes
Danger International,
Espionage,
Fantasy Hero,
Justice Inc.,
Robot Warriors,
Star Hero, and
Western Hero.
