I've got G2 as well as a few other sims. The hardest thing for me was to figure out where the runway is once you have taken off. The 'look down' feature in G2 isn't as helpful as I hoped, as it doesn't always zoom back in on the aircraft.

I've figured out the landings in Realflight park by looking at the landmarks. By recognizing the trees and noting the position of the windsock, I can find the runway pretty easily now. Taildragger take-offs in G2 ( and other sims) are way too easy.

Its the aerobatics I have trouble with. Once the plane is airbourne and above any landmarks, it difficult to judge what orientation its in...

In short, real life is easier, but costs more if you make a mistake...
