I think you may have already come to this conclusion, so I may be belaboring the point, but if you have any plans to approach this sim the way it is "meant" to be flown, game mode is literally a waste of your time. When you switch over to sim mode, you'll find that you still need to learn basically everything, as well as un-learn what game mode taught you.
Welcome and enjoy! And say "goodbye" to your friends and family for a while!
