I didn't take anything in your posts as offensive, don't worry.  :) I think that FSX leaves a lot to be desired, but I also think that the package still is the best one out there, although I'm really interested in all fresh approaches.

On some points, I also think that the criticism is ok, but also points to the need to look into solutions which are available. As said, one big advantage, maybe even the, is the open structure of the thing. This leads to some resource problems if people add too much, but also allows some smart devs to jump in and make it better on certain items.
