How the sandbox works Procedural generation and synthetic rules ＋

The terrain is generated from layered deterministic noise based on the world seed. Climate, resources and civilization placement use the selected world settings.

Population, technology, city growth, cooperation, conflict and disasters evolve through simplified fictional rules. Nothing here represents or predicts real-world societies.
