FWIW, I have a little different take when it comes to the value of programs like MSFS. Let's see if I remember this correctly, when it comes to teaching and learning, the law of primacy deals with things first learned being best remembered. If those first things happen to be wrong, then the student has a bunch of catch up ball to play. I think that the simulator games on the market can be pretty realistic, but there is also a very great danger of putting yourself in a situation where you teach yourself - and then repeatedly reinforce - improper and incorrect ideas, principles, techniques, etc. The result is that it often takes lot of extra time (read extra $$$) helping them to unlearn all of the bad habits s/he has developed. This is not to say that the sim games can't be used to some advantage, they can when their use is adequately supervised.
That being said, my personal advice for all of you who hope to become pilots one day is rather than spend 100's of hours playing games on the computer, spend the time flipping burgers or whatever to earn money for real flight instruction.
