GURPS

Gurps was not designed by Diratia Productions, but the Diratia Extension is. The Generic Universal RolePlaying System, or GURPS, is a tabletop role-playing game system designed to allow for play in any game setting. It was created by Steve Jackson Gamesand first published in 1986 at a time when most such systems were story- or genre-specific.

Players control their in-game characters verbally and the success of their actions are determined by the skill of their character, the difficulty of the action, and the rolling of dice. Characters earn points during play which are used to gain greater abilities. Gaming sessions are story-told and run by "Game Masters" (often referred to as simply "GMs").
