Star Civilizations is a colony builder for the near future. You run the UK space programme from a spaceport on the coast of a struggling Earth.
Build on Earth
Claim land in seven-hex parcels, then build power, homes, farms, labs and industry. Coal is cheap and dirty. Solar is clean and follows the seasons. Pollution drags Earth’s Health down and Health sets how much the planet can make. Push it too far and Judgement Day ends the run.
Then the Moon and Mars
Grow from Outpost to Town and the launch complex opens. From there the colony reaches the Moon and Mars, where domes live or die by their power, water and oxygen. Something is buried out there. It has waited a very long time.
Where it stands
The Earth colony runs end to end in the current build, with seasons and weather, laid water pipes, colonists and three colony tiers. Roads and local smog are going in now. Launch and the Moon come next.
An idle edition is also in development for phones and Steam. Every planet becomes an idle generator and humanity grows one tap at a time.
