Acting as a Commander in the Space Voyage fleet, players construct, crew and kit out a ship to voyage amongst the stars, seeking out rare minerals, avoiding alien races and trying to return to Earth as the richest Commander of the Fleet. You start by trying to complete your ship, which is mostly a luck-driven process, before launching the ship into the void. Once launched, players try to land on mineral rich planets, but there are many hazards to avoid. The game ends when at least two ships have returned to Earth. At this point there is a final semi-random determination of each player's holdings. All loans are settled and the winner of the game is the player with the most money.
