The marketplace already offers a Washington D.C. upgrade, i bet Microsoft/Asobo won’t interfere with their “customer” here and focus on other parts of the US. We shall see.
I did get the DC add on and I am pretty impressed with it. I should have tried it before I added it, I guess I could disable it and see. Once a lot f fixes are done with aircrafts and such, I would like to see improvements to the larger airports and the scenery around it. That said I always liked the addon airports by the 3rd party. I am still waiting for KSNA, KPSP, and KSAN and others, the 3rd party always added additional updated scenery around the airports kind of like what DC did with updating the airports as well. In time I would like to see more scenery addons like DC and maybe some of 7 wonders of the world
There is a nice freeware addon for DC.
