=== Biomes ===

The world is divided into four [[Biomes]] based on real-world climate data: [[Wood Biome|Wood]], [[Stone Biome|Stone]], [[Earth Biome|Earth]], and [[Arctic Biome|Arctic]]. Each biome determines which resources are locally abundant, what materials buildings cost, and how efficiently production operates. The Wood biome favors {{Icon|Wood}} production, Stone excels at {{Icon|Stone}} and {{Icon|Ore}} extraction, Earth leads in {{Icon|Earth}} output and {{Icon|Glass}} production chains, and the Arctic offers no raw resource extraction — serving as a challenge mode with doubled housing costs.
