The Crust
A lunar base builder about mining, automation, research, trade with Earth, and turning a Moon colony into humanity's lifeline.





The Crust sits between automation and colony management. It earns a slot because its core fantasy is building and sustaining a Moon base: mining, crafting, power, research, production chains, Earth trade, and a narrative about survival beyond the planet.
The Crust belongs in the catalog because it pushes the core colony-sim question: can a settlement keep functioning when people, resources, environment, and bad timing all collide?
Core mechanics
People pressure
Colonists, settlers, crew, or citizens create needs and priorities that turn a base into a social system.
Base planning
Rooms, storage, production, defenses, temperature, oxygen, water, or logistics decide whether the settlement works.
Failure stories
The best run is rarely perfect. Shortages, bad layouts, events, and cascading mistakes create the memory.
Long-term arc
Research, expansion, seasons, raids, diplomacy, or self-sufficiency give the colony somewhere to go.
