Heretic, you did read what I have posted?
Overlooked it or something.
I do have Austria Pro for both (!!)-FS9 and FSX as well as Ultimate Terrain Europe!
the limiting factor here and this is what we were talking about, is the airport sceneries!
Well, and as I said...for missing airports, there's always DIY. There's easy to handle programs out there with which you can at least place some standard objects to breathe a bit more life into the default airports.
For real-looking terminals there's GMax and Gimp, both freely avaiable. Granted, you need to get into them, but at least you'll be busy enough not to complain every second about the lack of add-ons for your desired area (not specifically aimed at you, more at the whole community).
And no, there's no excuse for not at least trying. For questions, there's FS development communities out there and for starters, some tutorials.
The only issue might be time, but as many successful (freeware) developers have a job and a family and still manage to pump out their add-ons, it's not a really valid argument.
So go out there and become a FSX developer. Even if you're just doing it for yourself instead of others.
