Play Simearth: The Living Planet Online

SimEarth: The Living Planet is a life simulation game released in 1990 for the MS-DOS platform. Developed and published by Maxis Software Inc., it falls within the ecology and nature genre. The game presents a top-down view of an entire planet, providing a broad simulation environment.

In the game, the player assumes control over a planet's development across vast geological and evolutionary timescales. Starting from various pre-set scenarios and world types, the player manages multiple systems, including the development of life forms such as dinosaurs, birds, insects, fish, and even machine-based life. Core gameplay involves directly editing the planetary environment by moving continents, altering weather patterns, and triggering natural disasters like earthquakes and tidal waves to reshape the world. These actions consume a limited pool of energy that must be carefully managed and replenished over time.

The player's objective is to guide the planet and its inhabitants through different eras, observing the long-term consequences of their interventions on evolution and the ecosystem. Progression is measured by the survival and complexity of life, with the simulation tracking changes over millions of simulated years. The game systems integrate geological, climatic, and biological models, requiring the player to balance energy expenditure with strategic planetary management.
