big hell no for me ,i want to see the terrain at night and dungeons.
Then use a torch, light spell or nighteye, ever heard of those things before? They're useful for seeing when it's dark.
I should need to use these things if I'm going to explore dark places, otherwise, then having them in the game at all is pretty much pointless, not to mention it really doesn't help the atmosphere when a supposedly "pitch black" dungeon is actually only as bright as being outside during a cloudy day. The lighting outside is somewhat less important to me, but even so, I'd like to see darker nights. With the level of darkness depending on the weather and moons at the time. No more walking around on a cloudy night where no stars are visible, and yet being able to see everything as clear as day. In Oblivion, torches, light and nighteye were pretty unnecessary to my by default, because without them, I could still see without problems even in the darkest places, the only time they were really nice to have around was when looking for hard to see objects. In Skyrim, I want some form of light, magical or otherwise, or something like nighteye, to be mandatory. To judging from the screenshots seen so far that depict dungeons, it looks like we're going to need a Darker Dungeons mod again.
Never adjusted the monitor brightness down, because then eveything would be dark, even when light sources are present underground.
And that's why the idea of adjusting the brightness doesn't cut it, because it affects the brightness even when it's supposed to be dark, and I don't want to make the brightness of noon under clear weather look like it should be cloudy so my dungeons actually look like dungeons.
