Night?
Why stop there. Get rid of Icons. Then along with "E-night". Put in real clouds. The kind where you have to have some knowledge of how to fly on instruments only. Get rid of the current "GPS Moving Map" and give us only a map of the arena and let everyone learn how to navigate using pilotage and dead rekoning. Add in real wind, and throw in some moderate turbulence below say 10 k. Now try to keep your gunsight on target!
It would be fun watching people try to land low wing taildraggers, with a cross wind.
YUP!! that would get almost EVERYBODY to log off. It would be way too realistic.
I say no to night.
