There are some really helpful answers and links above. I'd like to add something. Let me point out some differences between real live aviation and Flight Simulator X. When you're flying a plane on Flight Simulator X, you can do whatever you want with an airplane. You can cruise at an altitude of 500 feet AGL at 320 KIAS, extend landing gear and flaps to full when you're cruising at 36,000 feet with no damage, recover a stall using a nose-up input, touch down at a descent rate of 1800 feet per minute with flaps set 0, come to a complete stop after touchdown just by pulling the parking brakes(without engaging the reverse thrust or spoilers) and taxi around the airport by steering the nose wheel with the yoke just the way you steer a Grand Cherokee. Nobody asks you why. You may use any tabletop simulators for fun or to learn to fly - but be advised that you'll go about developing a set of unorganized, unclear information and terribly wrong concepts that will confuse you when you learn the real concepts of real live aviation because you don't learn things in a proper order. But it's okay if you keep yourself updated with how things work in the real world. I think it would be great to fly if they have a simulator cockpit and controls. But still, it's not something that I know with which you can log flight hours.
