My tech support cohort and I played this game in '86 for hours on end. It was totally engrossing and enjoyable. We compared notes, and tips on how to proceed in the game. Yes, sometimes it was fun to start the game without the right access code and see how far you could get before the Galactic Space Patrol located and destroyed you. Go ahead, in the space station, take a bit of extra time and have the character on the screen tapping his foot in annoyance, waiting for you. I only left the game when I discovered the Ultima series.
