Star City has a nice, evocative beginning. It's no wonder it was nominated for an XYZZY for Best Setting. You end up exploring a vast, cylindrical space station, like a simplified version of the Starcross spaceship. Its origins and your means of getting there are highly, intensely original and fun.
The gameplay is a bit uneven, and the scoring as well. Some events are worth 5 points; one is worth 50; and you reach 100 before the hardest part of the game!
That hard part is a flight simulator. It requires some guesswork, some examination, and some knowledge of how airplanes work. Surprisingly difficult, given the rest of the game,
It might be worth it more to play just up until the simulator, then use the walkthrough.
