This is not a flight sim topic....and while we generally try and discourage people from asking questions about sims in here (cause real pilots generally have no clue about computer games)
In this case it's a good thing you asked here cause you actually get to hear what real pilots think about these games. (which I think you need to if you want to fly for real someday)
So to answer you, it's good you have an interest in aviation. But personally, if you have any actual plans to learn to fly for real, I would actually advise against using sims for the most part. Cause past the absolute basics the $50 sim games you can get from best buy are a waste of time to try and learn from.
In fact, you can actually pick up a number of bad habits from them that you will have to unlearn when you actually start real flight training. So really trying to learn from them can hurt you more than help you in the long run.
So really if you do plan on playing them. The biggest thing is that you need to know is to always remember that IT IS JUST A GAME!
And I know a lot of FS people will have a problem w/ me saying that,
(we always do from the FS people that troll on here)
But you/they need to realize that really everything about an FS is basically not real since it is all just code and software (including flight dynamics and physics) and even if the programmers tried to get it very close to real world, it's still not going to be exactly the same as it is in the real world.
And so (among other mistakes you can make)I know for a fact having dealt w/ FS people before you can easily end up making yourself look pretty stupid when you try to talk to real pilots (or really anyone w/ actual aviation knowledge) about problems and situations that you had in the game that never actually happen in real life.
