I played it for the first time in a while recently. I've had it, but haven't been able to play it due to joystick incompatibilities, but I fixed that. It's a very good game. The Learning Center has lessons that you can read, and then fly them. The lessons are written by Rod Machado, an experienced pilot and teacher. The interactive lessons are extremely well done.
If you get this game, I'd also recommend that you also have a joystick. If you don't already have one, get one. It's a lot harder flying in an atmosphere with lift and drag than it is flying in space, for you Star Wars players, and possibly other games. You'll learn how to fly an airplane using instruments only, without using them at all...You can fly anything from an Aircreation Trike Ultralight to and Airbus to a helicopter. It has a variety of missions, all of varying levels. There's beginner, intermediate, advanced, and expert. You can do anything from give someone a ride to go flour bombing. All in all, a very good game that I'd recommend.
