What is a colony sim?
A colony sim is a management game about keeping a group alive through indirect control, base planning, resource pressure, and emergent events.
The genre overlaps with city builders, survival games, life sims, automation games, and fortress builders, but its signature is intimate failure: you remember the people, not just the layout.
What is a colony sim?
You do not control a hero. You shape the conditions, and a handful of fragile autonomous people try to survive inside them.
Part city-builder, part survival game, part accidental drama. You assign priorities, build the base, manage food, heat, mood, oxygen, and defense. The game supplies the disasters; your colonists supply the chaos.
Autonomous people
Colonists, dwarves, duplicants, settlers, or crews act through needs, work priorities, traits, skills, and schedules.
Survival economy
Food, heat, oxygen, water, tools, power, morale, and defense turn logistics into pressure.
Built space
Rooms, workshops, farms, stockpiles, pipes, walls, beds, gates, and storage shape what the colony can survive.
Emergent drama
Events, weather, raids, injuries, mistakes, shortages, and strange personalities produce stories the designer did not script.
The colony-sim loop
// the cycle that produces the storiesLand
A small group arrives with too little shelter, food, power, or knowledge.
Assign
Jobs, priorities, rooms, and stockpiles turn intent into a working plan.
Stabilize
Food, sleep, safety, mood, and infrastructure become the first victory condition.
Expand
New rooms, tech, workers, production chains, and risks make the colony useful.
Recover
A bad season, raid, fire, leak, or breakdown rewrites the next plan.
The loop never really ends: every story rewrites the next plan.
