This is the most acurate terrain, roads and landmark program of all the flight simulators because it uses Google Earth satelite imagry.

It only has two airplanes, a F16 Viper and the Cirrus SR22 so it is best at looking at the terrain and landmarks. This not for learning to fly but for learning routes and specific areas and landmarks.

Here is a video of the basics for setting up Google Earth Flight simulator:

Overall the simulator is fairly simple in terms of control, but the striking difference is flying over real satelite pictures of locations. This is the best flight simulator of actually presenting real objects you observe in flight.
