"A superhero roleplaying game¸ later (in the 4th edition) converted to a generic universal system (aka the ""HERO"" system). Action resolution is roll under skill on 3d6¸ with special target numbers for combat (11 + offense - defense) and pure attribute rolls (9 + attribute / 5). Character creation is an innovative open point system¸ the first of its kind. A pool of points can be spent on attributes¸ skills¸ and on customizable superpowers. The power design metasystem is a complex but highly-regarded piece which can be used for almost any power. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
