I actually used to *like* the night.. I could see/fight fine in it without playing with any gamma settings.. the icons are a real help to let you know where you are supposed to be looking for enemy planes when they are several K away.
I'd like to have a "true" night environment someday, maybe when TOD rolls around they'll have night for 3 hours a day or something to let the RAF do their night-bombing thing (Japanese did it to, as did the Russians and Germans).
How I'd do night-
1. Keep icons for night-fighters. Planes that had inflight radar now should keep normal icons instead. Planes that didn't have in-flight radar should keep icons inside of 1k, that wat if they find someone they can still engage them and fight.
2. Bombers that historically had radar jamming cal instead "jam" icons... instead of showing at 6k, they'd show at 3k or less.
3. Obviously, introduce night fighters. Beaufighter, P-61, 110 (C and G versions), maybe the He-219, Ju-88G. Don't know if the Russians or Japanese had any dedicated night fighters.
For the current MA, I'd really like the dawn/dusk cycle to be lengthed, so we get more "day" and less "dawn/dusk".
