The fourth edition of GURPS Space was released in 2006, and covered the creation of star systems, worlds and alien races, either completely randomly or with any amount of gamemaster intervention during the process.

He concluded by giving this a perfect rating of 5 out of 5, saying, "GURPS Space is ideal for any referee who isn't satisfied with existing SF systems and wants to design their own or to convert a favourite book into a rolegaming environment [...] Every SF referee should have one.
