Hi Steven,
Thanks for another excellent review for what seems to be a fantastic rendition of KSFO, which I will certainly purchase in the very near future. Regarding the absence of the city buildings, and while awaiting a potential add-on pack from SFD, I read on the dedicated .org forum thread that it's possible to install this pack on top of the freeware one, which includes the city, thereby alllowing the city part of the freeware pack to be seen. Sounds like a good idea, will definitely try it when I get the payware.
