You pose interesting questions. I'm not sure if FS2006 is something
that will be announced.... However let us assume that it will be! -
There are one or two things that I would love to see improved upon.

[*:c66ee12d98] I still want to fly over the poles! -
LA to Tokyo would certainly be more realistic. The chances of them
fixing that.... hmmmm... close to zero!
[*:c66ee12d98]More functional loading and ATC. - I.E real world
diversions. With FS2004 I can be in my Cessna 172 in a snow storm and
the ATC will still clear me to land! (Take-Off off course is another
story - although even setting the weather to extreme all I get told
is that I need IFR rather than VFR if I call the tower for
clearance

I'm sure as this thread grows we will find ... many ..... many more
ideas and suggestions.
