SimEarth puts you in complete control of a planet. Along with the modern day Earth there are a number of other planet scenarios for you to command. If none of those are appealing then a new planet can be created. Creating a new planet allows you to watch it develop from the very beginning of its birth. Land masses appear and disappear. See life-forms begin to evolve. As time progresses you can get involved in the planet forming process. Send meteors, start earthquakes, and cause volcanoes in order to create new land. Place plant and animal species in different environments. With the click of the mouse a variety of charts and graphs can be obtained. Watch how each one of your choices affects each area of the planet. SimEarth literally puts you in control of the world. ~ Jonathan Sutyak, All Game Guide
