Although we all know there are people doing just that, one must not automatically see complaints as something negative.
And every sim has its faults, we all also know that.
However, a flightsim is a complex piece of software, simulating complex machinery in a complex environment. In short; making flightsims is no easy task!
I grew up together with flightsims. My experience with flightsims dates back to the mid 80ies. Had someone told me back then that flightsims would be anything resembling what we have today, and that I would earn my living as a pilot, I would've laughed.
Looking through youtube videos of what sims looked in the early days, I can't believe that I actually spent hours on end, thoroughly enjoying playing with them. But I did! It was great! I learned a lot, and I played a lot.
Being a aviation nut probably helped, but I still can't explain why my enjoyment with flightsims has been almost unchanged, through the years. I guess it has something to do with making do with what you've got.
I have always focused on the positive about a sim, and enjoyed that. Ok there was an occasional lemon, that was tested and discarded, but most flightsims had some parts that I could enjoy.
This is true even today. Sure, there are things I'd like to change in every flightsim. But I am enjoying playing with them even so, because there's so much more positive sides, than there are negative...
