City Mover mod for Civilization VI.
Just an experiment on movable cities. Create the project “Hey Ho Let’s Go” in your city. This will create the unit city on wheels. Move the unit to some plot where a city can exist and “voila”! Should copy districts and buildings, but not wonders. Just choose where the districts will be placed by using the construction queue and they will be completed. Not all city details are copied. You can also flee an attack… be creative.
