If I think of the difference between driving a car and playing a car game, they are rather different, but somewhat related.
For once, I can speak with some authority here
Throughout my teenage years, I mucked around with flight simulators. A lot of flight simulators. From instrument-only 737 simulators, to the latest fighter jets and gunships, I did them all (also a fair bit of r/c aircraft, but I digress).
In my 20's, I started taking flying lessons. And when I sat in the plane... I found I could fly it. Pretty damn well - I was doing stall recovery and landing patterns in the very first lesson. There were a couple of new controls (you generally don't worry about carb heating on a flight sim, and trim tends to be automatic), but they were easy enough to cope with.
The two main differences?
1. The weight of the controls. PC sims are, by their nature, effectively all fly-by-wire. A Piper Tomahawk does not have that
2. The movement of the air. Flying straight and level on a PC is simple and hands-off. In a real plane it... just isn't!
Anyway, after that I became a firm believer in sims prepping you for real life.
