Gaia Maker is a planet-wide simulation game of terraforming, based on real physics and geology. Become the planetary overseer and use advanced planetary engineering to terraform lifeless planets into lush green worlds. How the planet develops is entirely up to you.

Various factors across the entire planet, such as insolation, temperature, atmospheric composition, and the carbon cycle, are dynamically simulated based on real physics and geology. Every action the player takes affects all aspects of the planet's condition.

Players are given various means for terraforming. Construct Dyson swarms to secure needed energy, build giant mirrors to regulate stellar light, and produce oxygen necessary for life with oxygen generators.
You can have animals inhabit planets with suitable environments. Furthermore, you can evolve some animals, granting them civilization.
The development, wars, decline, energy consumption, and planetary impact of civilizations are also meticulously simulated. Civilizations start in the Stone Age and progress until they gain the technology to harness fusion. Players can also influence the population growth and energy consumption of their civilizations, and observe how these parameters affect the evolution of their civilizations.

Starting on a planet with existing oceans makes terraforming very easy. However, planets with harsh environments for life, such as ice planets or desert planets, require a slightly different approach to terraforming.
