Flying over 'real terrain' is essential for me personally. No fake allowed even if there are image flaws. I want to learn about geography and the real world while I am flying. I've been able to virtually go back to some of the places I visited before:
Here is near Nice, France.

Here is Venice, Fl. There is a dog park near the airport where you can swim or run with pup and watch the cows come home. It's a crappy small parking lot and thin bit of beach and difficult to find.
Here is Paris of course losing my virtual pilot's license. Actually an allied pilot once flew through it during WW2. The Golden Gate Bridge was also barnstormed.
