I know its been requested before (and probably before that too!) but I would like to bring it up again. Basic middle eatern buildings haven't changed much in thousands of years, except in the heart of more urban areas. So one set could easily accomodate times from the pharoahs to the present, maybe with just optional windows and doors and roof accessories to diffrentiate the different eras.
I am in the middle of such a project myself using stuff from other companies and that I have made myself, and it would have been so much nicer with WWG
