I bought Finkenwerder and before you buy it I wanted to give you some information on the scenery from Dieter Kreiskott.
First of all having the purpose of donating the money is so awesome and is definitely more needed on the Flightsim market.
Though the airport isn't really what I thought it was. I don't think that it is bad. No not at all, but let's say, that I expected a different product from looking at the screenshots.
Starting off on the runway. It is a default runway which I didn't expect when looking at the screenshots posted on their webiste.
All the taxiways are just copy paste from Google Earth and aren't actual taxiways. That is really annoying when taxiing over the apron because that is like when taxiing over default gras in P3D.
Everything around the airport (photoreal scenery) is very blurry too.
Also half of the planes standing on the apron are somewhere bugging in buildings.
You cannot say just bad things.
I really like the work of the hangars and buildings standing on the airport. They are highly realistic and well done.
Also many ground polygons are available and letting the airport feel alive.
Also you can find static traffic on the apron. There are e.g an 380 and a Beluga.
Having Finkenwerder for P3D and FSX you can now finally fly the Beluga or test Airbus flights from a beautiful designed airport which cost's way less than different scenerys and also has a good purpose.
Let me know how you think the airport is.
I have some screenshots attached so you can understand what I just wrote.
Thanks and have fun flying,
