Aces High is quite a nice sim, for the daytime anyway. The night leaves a lot to be desired.
A few suggestions:
At night the Icon range should be lowered to about d1.0.
Would put those nice night cammos on most luftwaffe aircraft to good use.
Some aircraft were dedicated night fighters with radar (Bf110?). For these aircraft the icon range remains normal (upto d6.0?)
Also silver aircraft can be seen better, maybe bombing missions will use the Lanc over the B17s at night, like in real life.
Would be nice if we had a seperate cockpit light. The effects from the auto trim lights n the gun flashes are superb but i hate firng my 50cals just to see my altimeter (especiall when in a shadow). A bit of background lighting in the cockpit is needed.
Lastly a few search lights on bases. When base is not under threat they highlight the runway. When under attack they look to the sky and "lock on" to enemy bomber formations? leading to perhaps a slight improvement in ack accuracy on lighted bomber group?
Just my two cents.
