I believe the greatest mistake many of us did - me included, was to become too attached to this flight sim.
Perhaps because we invested so much effort and time on it, we started to feel too attached and emotional.
Clearly that was a mistake - and we were taught a harsh lesson for it.
The good news is that, thanks to that lesson, we (or at least me) discovered that there is a whole world of flight sims out there, waiting to be discovered and in consequence, we put this flight sim (DCS etc. ) in its proper place.
