RimWorld
The reference sci-fi colony sim: a small group of crash-landed survivors tries to build a home while an AI storyteller turns logistics into drama.
RimWorld is the core benchmark for RimWorld-like games because it ties every system to colonist needs, injuries, moods, traits, relationships, prisoners, animals, weather, raids, and long-term survival. It is less about perfect optimization and more about keeping a fragile settlement alive while emergent events create memorable disasters and recoveries.
RimWorld 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.
