My son is a U.S. Air Force pilot, and he says it's an excellent simulator. It's advanced enough for him, and yet simply enough for me to enjoy!
BUT,....and it's a big but, it takes some horsepower to run it. Unless your machine has a fairly decent cpu, enough memory, a good graphics card, and preferably an SSD, you'll find lengthy load times, and choppy performance.
Use the "recommended" hardware performance requirements, as your "Minimum Requirements", and go up from there. Also requires a decent joystick.....using a mouse is ridiculous.
