That's what I think too. The -200 has been done by two software companies before -
after all, is it so beautiful that it keeps one flying for hours and hours?
Concerning what is really needed - I think the 300/400/500 versions would
bring more enjoyment to todays flightsimmers. IXEG has a fabulous one
under development, however, its only for Xplane. The Wilco 737 is outdated,
the sound is bad, the autopilot cannot turn to a heading without overshooting
it and the grahics are outdated. Still I think the major reason why there is
no good -300 out there, is the complexity of its systems.
Just my 2 cents...
