SimEarth

SimEarth: The Living Planet is a life simulation game, the second designed by Will Wright, published in 1990 by Maxis. In SimEarth, the player controls the development of a planet. English scientist James Lovelock served as an advisor and his Gaia hypothesis of planet evolution was incorporated into the game. Versions were made for the Macintosh, Atari ST, Amiga, IBM PC, Super Nintendo Entertainment System, Sega CD, and TurboGrafx-16. It was re-released for the Wii Virtual Console. In 1996, several of Maxis' simulation games were re-released under the Maxis Collector Series with greater compatibility with Windows 95 and differing box art, including the addition of Classics beneath the title. SimEarth was re-released in 1997 under the Classics label.

== Gameplay == In SimEarth, the player can vary a planet's atmosphere, temperature, landmasses, etc., then place various forms of life on the planet and watch them evolve. In the "Random Planet" game setting, the game is a software toy, without any required goals. The big (and difficult) challenge is to evolve sentient life and an advanced civilization, culminating in that species leaving the planet in an exodus. The development stages of the planet can be restored and repeated, until the planet "dies" ten billion years after its creation, the estimated time when the Sun will become a red giant and kill off all of the planet's life.
