Flotsam
A floating city builder about rescuing survivors, scavenging a flooded world, and keeping a drifting settlement alive.
Flotsam brings colony management to a bright garbage-sea setting. The player leads drifters, collects debris, rescues people, expands a floating town, and moves between soaked ruins and industrial remnants in search of resources.
Flotsam 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.
