Star Trek II: Starship Combat Simulator
Star Trek II: Starship Combat Simulator was a supplement for  (RPG) by FASA, and conceived as a tabletop strategy game. It was for this game specifically, for which FASA embarked on the production of their highly popular line of pewter starship gaming miniatures as game-enhancing expansions/supplements. In concept, it was similar to the Star Fleet Battles strategy game by FASA competitor(s) Task Force Games / Amarillo Design Bureau, launched four years previously. 

This was a standalone game and it was not necessary to own FASA's main RPG to play, and the game box set was therefore usually sold separately. Nonetheless, the game contents of its to Star Trek: Starship Tactical Combat Simulator retitled second edition, released three years later under the same catalog number, were included in the "Deluxe" version of the 1985/86 main RPG second edition reissue, as an extra bonus component. 

It described combat for starships and differed somewhat from not only the original RPG combat rules, but also from those of FASA's own in 1984 released Star Trek III: Starship Combat Game (No. 2006, reissued in 1985 wich incidentally, was the game included as bonus in the early issues of the "Deluxe" version of the main RPG), the Combat Simulator served as the template for.
