This is an airline simulation game, not a flight/airplane simulation game.
You don't do any flying; you are a CEO of an airline, not a pilot.
AirwaySim is a business simulation where you compete against other players who also are running their own airline business. You will do things like schedule routes, choose aircraft types, manage finances, and other business things that are required to manage an airline. This game is definitely not for everyone, but if you like business simulations, or think you might like the genre, and have a fascination with airlines, then this might be just the right game for you.
