Ok, I'll explain this:
Neo City:
One of the multiple cities. In that category you will have access to the various locations in Neo City. They are as follows:
Industrial Island
Midtown
Downtown
Uptown
The island is just that, an island off the main land. Construction Projects happen there. The rest are self explanatory, filled with normal buildings, some houses, etc. If you want your character on the island, you post there, etc.
