SimEarth: The Living Planet

SimEarth is a planet simulator - a model of a planet. It is a game, an educational toy, and a fun tool. With SimEarth you can adopt many of the included planets or design and create your own. SimEarth treats the planet as a whole: the living climate, the atmosphere, and the planet itself - from soil and rock to molleton core - all affect each other. You see your planet as a whole - from a satellite's point of view, at two magnification levels. SimEarth can be played in two modes: Game and Experiment. In game mode, you try to develop, manage and maintain your planet within the allotted energy budget. In experiment mode, you'll have unlimited amounts of energy to shape your planet. Thus, you'll be able to set up any development level and then introduce new factors to see what happens. In this mode, SimEarth is a "planetary spreadsheet". Your SimEarth planets are populated by electronic life forms called SimEarthlings. SimEarthlings range from single-celled plants and animals to intelligent species. Intelligent SimEarthlings are not limited to humans - or even mammals. There can be intelligent dinosaur SimEarthlings, intelligent mollusk SimEarthlings, and even intelligent insect SimEarthlings - but only one intelligent life form at a time. A single planet can be populated by billions of SimEarthlings. Their welfare is in your hands.
