It came out in the mid 90s for DOS. It is NOT Space Quest. You fly around in your ship in outer space and along the way you can run into other pilots or go to other planets. To get to another planet, you would be given coordinates and you would have to fly there manually. You had a limited charge of some substance that allowed you to travel at great speeds for commuting, but if you were out you could fly there going your normal speed which would take ages.
