Star Control II uses a starmap as copy protection ("tell me the constellation at these coordinates..."). I lost the starmap at one point, but if you can remember just one of the answers, you can just keep running the game until that answer is the correct one. (The copy protection is at the very beginning, and the game won't bug you during play.)

Is this a factor if you're playing the Ur-Quan Masters?

No; I lost the starmap when I still had some 5 1/4" diskettes that said "Star Control II" on them.
