Planetbase
A compact space colony builder about settlers, domes, power, oxygen, food, mining, disasters, and self-sufficiency.
Planetbase is a clean older entry for readers who want the fundamentals of off-world colonization. It is about placing modules, keeping oxygen and power stable, producing food, mining resources, processing materials, and expanding only when the colony can support it.
Planetbase 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.
