About Gaia Maker
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.
Planetary Simulation
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.Terraforming
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.Animals and Civilizations
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.Diverse Planets
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.Features
- Simulation of the entire planet based on real physics and geology.
- Detailed simulation of temperature, biomass, carbon cycle, insolation, and atmospheric composition.
- Dynamic gameplay where player actions impact the entire planet.
- Resource acquisition via fusion reactors, Dyson swarms, and more.
- Various facilities and methods for terraforming (e.g., oxygen generators, aerosol injection).
- Animal breeding and habitat expansion.
- Simulation of civilizations' evolution and their planetary impact.
- Various dynamic events affecting civilizations, such as plagues and wars.
- Multiple distinct planet types to terraform.

If you enjoyed Simearth, this is going to scratch that itch.5 found this helpful
Gaia Maker is a great free game to spend time. At first I couldn't understand but after I got the hang of it watching and growing civilizations and planets was so cool. Overall, I hope this game continues to get updates and new features. One thing to note: I feel like the game is too easy (especially if you know what everything does) when you speed it up. I wish it was a little bit more balanced on the difficult side. The game also doesn't require any high end device to run, as my HP Laptop (far from any good gaming PC) can run it easily with 150+ fps.3 found this helpful

A really cool game, maybe a bit simple but still, incredible, no lag problem and the only "bug" I found was when I clearly was just screxing around trying to spawn a volcano on each tile of the planet and well... yeah but still, good game if you have a couple of hours of boredom (also disrespect to the one guy that did'nt reccomand just because he think some other game is better boo him everyone)
my planet was too efficient and caused the fox civilization to flood my planet, so i set plagues and fires to limit their numbers to give other animals a chance, and caused a total ice age making everyone extinct. LOL. entertaining for a run or two, even if this style of game isn't your usual.
Fun game, reminds me of Sim Earth.
