Resources are buildings which supply Electricity or Water to the player's city. Other buildings, such as residential or infrastructure may demand one or more resource. Demand is shown next to the resource icon. Supply (max) is represented beneath the demand value.
As other buildings are built they will increase the demand for those resources. If a new building would cause the player to exceed their supply, the building will not be available for construction. Players may then choose one of the following options to allow further construction:
- Build another resource building of the type needed.
- Replace an existing resource building with a more expensive version (which provides more resource)-- this may require building the new resource building, then deleting the old one. This might be necessary, for instance, if the player is running low on space.
- Sell a property that consumes the needed resource. WARNING: There are other consequences to this decision not covered in this article (at least not at this time.)
- Move a property to the Warehouse.
