Do you mean pre-built stores for weapons and vehicles or just empy spaces in general? There will be many pre-built stores as well as plenty of open areas for you to build your own. ---Update: I am working on a teleport system so that all you have to do is walk up to the front door of a skyscraper and you will be teleported to the roof. I also might put in a subway system, which would just be a series of random teleports to help you get around faster.
