Microsoft Flight Simulator:

Microsoft Flight Simulator is the closest we've come to a near-perfect real-world game in the sandbox, and the latest update brings the goal even closer. Now you can travel anywhere in the world with Bing data, raising the bar for simulations to an unprecedented high.

 

An open world in the best sense that anyone can use or do whatever they want. Fly freely around the world, take part in competitive landings in some of the world's most challenging airports or simply travel; Microsoft Flight Simulator is an unparalleled achievement. Don't forget to use one of the best PC joysticks to make this flight test even more fun
