The Meaning of Life, the Universe, and Everything.
I have a theory... if you like void fog, please post up what view distance you use for normal play. I believe that those who like it are used to playing on short view distances. Nobody who plays on "far" could be stupid enough to like it, right?
Forced tiny viewdistance is atmospheric! Is everybody here insane?!
nope, only you. The way you decide to play is on you, this isn't a matter of "what is the RIGHT way to play". Notch made this so that you can play however you like to play...this is why there is no real objective in the game, and you can do whatever you like with your world and how you play it.
If you decide you want tiny view distance, never break a block, punch every monster in the face with your bare fists, by all means, have at it ... I however will have my view distance set to far so that I can enjoy the beauty of the random world generation when I'm on the surface, and enjoy being able to see from one side of my 100+ x 100+ x 4 strip mine to the other.
play on far myself I love it. Deeper you go into the earth the darker and dusty and dangerous it can get. Since Minecraft doesn't have cave ins (if they did wouldn't be a threat) what else would give any need to watch more carefully down in the depths of the world?
I play on Normal distance. I'd play on "Far" but that seems to like to cause crashes for me. I definitely prefer to be able to see as far as possible, especially outside.
That said, as for the void-fog, I can actually say I do indeed like the concept of it. I think that it is a cool idea.
But I can readily admit that there are inherent issues regarding actual practicality. Basically, it seems good in theory, but fails in practice.
First of all, I think it's a bit too pervasive. The fog color and render distance actually start to change at level 32. So that's 1/4 of the total available height that is affected. Granted, the effect isn't generally noticeable until much closer to bedrock, but it's there.
Second, as others have pointed out, it doesn't exactly work "right". If you look down at bedrock level from above the fog, you can see everything fine. But if you up from below, you can't. If it is supposed to be a true "fog", it wouldn't work like that.
And yes, third, it removes the ability to build large rooms near bedrock and be able to see them. I can understand the frustration this causes. I think that if void-fog had been in the game since the beginning, everyone would have been fine with it. The problem is that it's a bit too much to try to add now that everyone is used to being able to build epically huge things at bedrock level with no prior repercussions.
