Gamemasters (GM's) created their games set during the years prior to the Original Series (pre-TOS), the earliest days of the Original Series (TOS), the Animated Series (TAS), the Film Series (TFS), the Next Generation (TNG), Deep Space Nine (DSN or DS9), and Voyager (VOY), decades after the television series, or using alternate or Mirror concepts. Often, GMs drew source materials or established policy based on the RPG system Star Trek: The Role Playing Game, which was published and edited by FASA Corporation from 1982 to 1989. Each GM presented an opening storyline, rich in the technology and "canon" of the Star Trek era picked for his/her game, then the GM and players posted interactions, with the GM deciding the results of actions taken by the players.
While players were expected to create unique principal characters (PC's)--usually Star Fleet officers of various ranks--they often based the beings they played on physical characteristics established on Star Trek. Often the characters were humans or races (Vulcans, Andorians, Klingons, Romulans, etc.) established on Star Trek, but players were free to create their own races with distinct physical or mental abilities. Character development regularly resulted in close, even romantic, relationships between different characters.
A detailed Stargame_Help_File was created to assist new players and gamemasters learn to navigate both the administrative and gaming aspects of Stargame. For the original text of the help file, see Stargame Help File.
