From the back of the box" Expansion into the solar system! 1 January 2050: After many decades of research and development of space travel, mankind is now ready to reach out to the planets of the solar system to establish mining bases. The survival of technological civilization depends on the rapid and efficient utilization of the solar system's mineral resources to replace the rapidly diminishing supply of industrial minerals available on earth. For this reason, the United Nations has formed a Mining Council and empowered it to grant mining concessions throughout the solar system to anyone who can be the first to claim them. [...] PLANET MINERS gives you the opportunity to guide your family to a commanding economic position in the solar system. From one to four persons can play, with the computer taking the part of all the other families. This game can be played solitaire or with friends.
