Gold Key's Star Trek series was a real hit-or-miss game, with some stories that felt like they belonged in a Trek entry, and some just laugh-out-loud hilarious. They eventually lost the license to Marvel just before the movie, but this link here shows that there was to be one last comic, which never made it to stores.
It is called "Trial by Fire", and sees the Enterprise dealing with a energy dispute over the planet Orgone. While this certainly could have been an interesting story, one cannot help but enjoy the final printed entry, which featured an appearance by Harry Mudd, of all people.
