Q* (qstar) is an RPG Pen & Paper System, that tries to streamline and abstract as much as possible. At the same time, it's highly extensible because the base rules do not make any assumption about the setting (fantasy, western, scifi) you want to play.
The rules are kept as simple as possible while providing a certain amount of realism. For some of the rules, especially equipment, it's highly recommended to get printouts besides a character sheet.
Q* is under the Creative Commons BY-NC-SA licence. It's free and open source and you can contribute!
The rules and character sheet use icons from game-icons.net, and their respective authors: Lorc, Delapouite & contributors. The icons are provided as font by Game Icons Font.
