Here is my two euros worth:
I would willingly pay full price again for a fully upgraded model with improved engine modelling (perhaps like the Q 400 / Dash 8 - which I know is expensive to develop),
I would be dispointed to see any departure from the traditional instrumentation, and navigation (which I think may have been suggested by others) or automatic prefilght checks. Keep it authentic.
I would prefer not to have the manual appear on 'Shift 3' when I need to change views
LIke Bushio - I do not fly via Network - our internet speeds are not up to the job.
All the best
