From the ancient days of my teenage years comes one of the earliest space flight simulators - Tie-Fighter or its sequel, X-Wing. Of course, when you want to make a space simulator with space combat you're going to choose Star Wars as the theme for it. Sure, there's Star Trek, but we're talking about fighter combat and that's more about capital ships duking it out on a larger scale. Tie-Fighter and X-Wing are all about flying around in any direction in search and destroy missions to take out your enemy. What's not to love?
