I was never able to get into the Gold Key Comics. I started reading Trek comics around 1980 or 81 with the Marvel series. Still have all of my back issues of that, and also the first DC series. The DC series was my favorite.
DC also put out a Next Generation mini-series in the late 80's that I own, but I did not enjoy it at all. My Trek interests as far as collecting and reading ended for me in 1992 with "The Undiscovered Country". That was the last tie-in novel I read all the way through. If memory servers, I did get a hard cover copy of the Generations novel as a gift, but I did not find it interesting.
