After playing msfs in Vr for a while, I played a 2D flight and what struck me was that a was getting a much better since of scale.
The reason being that I could widened the focal length to see more of the landscape.
It really helps to get a good since of scale when looking from outside of the plane.
So if the mouse wheel worked in Vr or there was a setting in the menu to set the focal length to a specific value that would be very nice.
