1. As GM, open the Scenes sidebar and click Generate city.
2. Pick:
   • City: one of the fourteen.
   • Era: the 1980s (1986).
   • Area: the city core, or the whole metro area (about 30 miles across). Metro scenes are large and can be slow on weaker machines.
3. Click Generate scene.

The first time, the city's map is downloaded (one to a few minutes, with a progress bar) and saved in Data/kg-cities/<city>/. The scene then opens.

Refresh data only downloads a city's map again and updates its existing scenes without making a new one. Use it if OpenStreetMap has improved a city you play in.

City scenes are drawn at real scale: 100 pixels to 250 feet, with distances in feet and miles. Movement and measuring work as they would on the street, and KG Transit's travel times are right without any setup.

Each city keeps its own landmarks and label edits, so a campaign can travel between cities and come back to find them as it left them.
