It's a great ATC Simulator with clean graphics and detailed tutorial pages. You have to vector the arriving and departing aircraft in and out of the airport while maintaining the Separation, following Airspace Restrictions, managing emergencies, vectoring the aircraft to circumvent weather. All approaches are Instrument Approaches. There is nothing like Transition Level and no altimeter settings like QNH or QFE.
The satisfaction of properly sequencing the arrivals and orchestrating the traffic is super satisfying. Very easy to play for hours on end without realizing. Good Value for Money. Totally Recommended.
