The FASA Star Trek Roleplaying game established some really cool Trek mythology that was basically destroyed by TNG. While I enjoyed TNG, I was one of the people annoyed since I had been reading and playing with the FASA games for a few years by that point.
You could find these ads in comics in the 1980s. I would try and get my fellow comic book readers interested in a little Trek RPG by pointing these out, but they would never bite. Lots of dice were rolled alone.
