Ratopia
A side-view survival city builder where citizens, economy, exploration, production, and defenses shape a growing rat society.





Ratopia is a strong adjacent pick for colony sim readers who enjoy settlement economies. It asks the player to manage housing, taxes, jobs, production, exploration, defense, and social stability in a compact side-view colony.
Ratopia 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.
