World Shaper: Local Chronicles

A 2D god game on a spinning Earth with real rivers and lakes (the Nile, Amazon, Mississippi, the Great Lakes and hundreds more). Carve rivers, raise islands tied to any country, 60+ historic nations (from Ancient Israel and the Ayyubids to the Haudenosaunee and Haida) or theoretical ones like Pirates and brand-new Independent nations, dig lakes that connect to rivers, raise mountains or flatten plains, and place history-changing specials: ancient Roman roads, an unclaimed medieval castle, a UFO crash site, colossal ore deposits, a cache of lost books and artifacts, a two-way portal, a 25 km deep pit and world-famous natural wonders like a grand canyon or a peak taller than Everest.

Every change re-simulates elevation, winds, rainfall, temperature and biomes. Each country's GDP combines the effects of everything you've shaped, with a live world GDP ranking. The built-in Local Chronicle Engine writes a detailed alternate history, and the game's own Micro-LM varies the wording. Optional Enhanced storytelling retells each history with a small open-source language model (Qwen2.5) that runs entirely on your device via WebGPU: no AI service, no text sent anywhere.

Map layers: terrain, political, elevation, biomes, temperature bands and rainfall. Your world and every history autosave, and you can keep named copies.
