FSX/P3D. We'll got good news and bad news I suppose. The good news is, the upcoming Orbx NoCali will stretch far southwest enough to cover the Bay Area. The bad news? It mostly will not be compatible with US Cities San Francisco. I say this because Aerosoft's London is still not compatible with FTX EU and there doesn't seem to be any efforts on either side to get this to work. Many have, but only through a series headaches. Hopefully things will be different here without issues. But then again, after looking at FSDG's Thessaloniki's city scenery, would anyone want a city without night lighting? I'm glad to see Orbx in my back yard, let's hope many airports come with it as well!
