Fablewood Chronicles is an idle strategy game about a civilization of moveable regions that keeps running whether or not you are watching it.

You buy a region and put it somewhere. Every region type reaches a certain distance, so two placed within reach of each other open a road between them. Money cannot improve that road. It improves because people walk it, and a worn road is faster and kinder to the traveller on it. Wear enough of them in and the lines stop being lines: roads bundle into trunks, crossings collapse into junctions, and highways curve between the places your people actually go. Drag the two regions apart and the road between them is lost permanently.
