SimEarth: The Living Planet is a life simulation computer game designed by Will Wright and published in 1990 by Maxis, in which the player controls the development of a planet. Although the game was much admired when it was released, it was not a big seller compared to its hit predecessor SimCity. Versions were made for the Apple Macintosh, TurboGrafx-16 / TurboDuo, Commodore Amiga, IBM PC and the SNES (this version was developed and published by FCI in 1992). SimEarth is also Maxis' first title to feature built-in copy protection, where players, upon the first startup of the game, must submit a correct figure from the manual for one of several questions pertaining characteristics of planets in the Solar System.

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. Since it is a software toy, the game does not have any required goals. The big (and difficult) challenge is to evolve sentient life and an advanced civilization. The development stages of the planet can be reverted and repeated, until the planet "dies" 10 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.

The game models the Gaia hypothesis of James Lovelock (who assisted with the design and wrote an introduction to the manual), and one of the options available to the player is the simplified "Daisyworld" model.

The player's control of the planet in the game is quite comprehensive; display panels allow the player to regulate everything from atmospheric gases, with percentages to three decimal places, to the rate of continental drift, to the rate of reproduction and mutation of lifeforms. In addition, the player is given options to place equipment or items that interfere with the planet's development, such as Oxygen Generators, which increase the amount of oxygen in the atmosphere, and the Monolith, a take on the one found in 2001: A Space Odyssey, which aids in increasing intelligence of a lifeform through extraterrestrial contact.

The list of disasters ranges from natural occurrences, such as hurricanes and wild fires, to population-dependent disasters, such as plagues and pollution. Effects on the planet may be minor or major depending on the current conditions. Increased volcanic eruptions, for example, increase the amount of dust in the atmosphere, lowering global temperature; earthquakes in a body of water may produce tsunamis; and the shortage of nuclear fuel for a nuclear power-dependent civilization may potentially trigger nuclear war.

All player-triggered actions have a cost specified in "energy units" or "omega (Ω) units"; for example, 50 energy units are required to lay down a single terrain square, while 500 units are required to lay down a terraforming device. The energy budget is determined by the level of development of the planet, and the chosen difficulty level; on the lowest difficulty level, the energy budget is unlimited.

Game play itself can be somewhat mystifying; species may thrive or die out for no apparent reason. Mass extinctions, however, are often followed by periods of renewed evolutionary diversification, allowing the player to experiment with new sets of species and ecosystems.
