aerofly FS is a flight sim for beginners and more advanced pilots.
The glider and ultra-light flight simulation is really rather good.
The sim can be used for training approaches and landings with single-engine propeller aircraft as well.
There are plenty of airfields and nice scenery from Switzerland to fly in.
The simulation is not that good for fighter jets, you need to look at DCS for high-quality simulation of those.
However, jets in this can be fun still even if not most accurate flight simulation.
The developers of aerofly also have different product for RC-plane and helicopter simulation and training (hook up RC transmitter to PC for example), if you aim at improving RC skills then that might be better choice.
Depending on what you are after this does have good points and value for money.
For relaxing and training with glider or ultra-light this is a good choice.
For combat with modern jets you need to look at other choices.
