Well, I kind of cautioned of the limited realism. The basic physics are there, not more, and the world is about looks, not functionality. This whole thing really only is about taking the plane out for a walk and watching the daylight landscape. In this it performs very well.
I told you so!

Twice! (post #3, too)
Take it for what it is. You can have fun with it if you do, and can learn about Switzerland

. But if you insist on your expectations being different, then you will recall it as a waste of money, which would be sad. that bad it simply is not.
I also saw that Steam sells the full package with 8 instead 4 planes, and for 40 bucks. Well, that much it wouldn't have been worth for me, too, probably. As I said, the special edition "2013" that I got, regularly costs 30 Euro, and I got it for the half. Originally the thing costed 65 dollars, thats why I did not go after it earlier this year.
I agree though that it is a bit rich that they promote this as the most realistic flight simulator". The most realistic VFR looks - that would have been correct. But again, I told about the basic physics only, and limited options.
