🌍 Gaia Maker

Gaia Maker is a physics-minded terraforming desk. You do not drop houses on a pretty coast. You inherit a barren rock and start arguing with its air. Carbon moves. Temperature follows. Composition shifts, and one morning the model admits there is weather.

The toys are planetary on purpose. Fusion plants and Dyson swarms are not victory screens. They are power bills for work done at globe scale: nudge the sky, seed a habitat, watch animals take a latitude you made habitable last week. Civilizations can rise in the numbers and fall in the same numbers if you treat the atmosphere like a slider instead of a lung.

Rust keeps the simulation fast enough that a careless click still feels like climate, not a menu. A green world is a temporary truce among cycles you barely understand. Push heat too hard and the truce ends. Starve the carbon path and the rock remembers it was dead.

There is no mayor’s speech. The question the globe keeps asking is smaller and worse: are you a gardener, or a witness with good instruments? Every decision ripples. Some ripples come back as forests. Some come back as silence with a nicer graph.
