Back when I was a wee lad, my parents bought a personal computer that ran Windows 3.1 and one of the early games I had was Star Control II: The Ur-Quan Masters. The game had a more explicitly "fun" starship-combat simulator I remember playing with my cousins and a prolonged story-based game that I never actually finished--I just kind of wandered around in the spaceship harvesting minerals from planets to buy ships and occasionally fighting the bad aliens.
