One of the moments I loved the most in Skyrim was walking around at night with the aurora borealis shinning in the sky above with the etheric soundtrack quietly lulling in the background. It was one of those little touches that I will never forget and will love the most for some reason.
I really hope there is something they have put into the game that creates a similar feeling. Obviously an irradiated borealis would seem the theme of the game, all green and glowy at night. Other things I'd like to have once in a while is thick fog hiding enemies around the corner in swampy areas or costal regions. A very few areas that are so dark you cannot see beyond the light of your pipboy, like a horror themed vault or the hunt for a murderer in an abandoned building.
What are some things you'd like to see added to the game (not gameplay mechanics but visual/environmental details) that would make the world come to life that much more for you?
ps. can someone edit out the typo in the title and change "and" to "an" pls & thnx.
