Okay, I'll start something here.
I'd like to see more than just clouds and a sun effects. Wouldn't it be interesting to have rain, fog, snow and other weather effects? Not only would they add visual interest to the game but would enhance game play since the effects of weather certainly had an impact on missions during the war.
And of course, spotlights over targets at night and some night fighters would be neat too!
Just thinkin out loud...can't wait for V2...
