Issue #70 (February 1983) contains a particularly memorable advertisement for me personally.
I knew -- and loved -- FASA because of their excellent support for GDW's Traveller. I was also a huge fan of Star Trek. So the news that there would not only be a Star Trek RPG but that FASA would produce it was like a dream come true for me. I played the heck out of this game and can still relate the events of many an adventure in vivid detail. If asked about my favorite roleplaying games, my standard response is that I actually have three -- D&D, Traveller, and Call of Cthulhu, in that order. But, truth be told, I suspect Star Trek: The Roleplaying Game probably deserves to be in that august company. What a great game.
