Guy W. McLimore, Jr. is an RPG designer and author. He was one of the main designers and writers on the Star Trek: The Role Playing Game line from FASA in the 1980s. McLimore began his career as a designer with an article in Dragon magazine from TSR. His first major work was as a co-designer for the Star Trek game with Greg Poehlein and David Tepool. He also wrote or co-wrote several supplemental books in the line, including a short story titled "The story of Lee Sterling" in the Cadet's Orientation Sourcebook.
By the time the second edition of the game was about to be released, McLimore found himself embroiled with his employer who wanted to further "militarize" the game: "Our primary editor rewrote a lot of the structure with this in mind to make it sound more like a military organization. I think we fought more over the Second Edition more than anything we'd ever done. We won some of those battles, and lost others." Feeling that the evolution was not in the spirit of Star Trek, he and some like-minded colleagues shortly thereafter stepped away from the game.  Reportedly, it was actually the increasing "militarization" of the game that became one of the two reasons for FASA eventually losing its Star Trek license in 1989. 
While with FASA, he also co-designed the Doctor Who RPG. He moved on to work for TSR for a while working with his Star Trek co-designers on the Castle Greyhawk set for the Advanced Dungeons & Dragons line. He also wrote a supplement for Top Secret S.I.. He continued to work with Poehlein writing for R. Talsorian Games before founding Microtactix Games with him.
