Trivia
If the player tried to steer the spaceship into the sun, the game would warn the player repeatedly and automatically correct the course to something a bit less suicidal. A dedicated navigator, however, could correct the corrections and, eventually, pilot a path to his fiery doom.
(A similar possible death was programmed in allowing persistent players to crash their ships into the inside of the "crystal sphere", a hard shell completely surrounding planetary systems in this fantastic cosmology).
