My impression of this reply is that you don't play this game, honestly - but ok, I will humor this post to some extent;
"Carry compass. If you don't have a compass, then just enjoy being lost, stay put until dawn, or play another server for an hour or two..."
So, you're saying that the NPE (new player experience) should be: a) buy the game b) install the game c) setup character d) join server e) sit and wait for 4 hours because of a black screen? (Hint; no, a new player would assume something is broken and switch server or in worst case scenario refund the game instantly)
"Are your sound settings not working correctly?"
How is sound going to help anyone see? I think you totally missed the point of visual indications in a game oriented around survival and pve/pvp.
"Dark and stormy nights are, shall we say, difficult and unaccommodating. Am I missing anything?"
Nope, you got that 100% correct. I suggest you do like me and go camping 3-4 times a year to experience stormy nights for real.
"Maybe you need to turn down your brightness to 50% or less."
This made me laugh a little.
"And please don't call us trolls just because we have learned to cope with an increased difficulty level in a game"
I'm not calling you a troll, I'm simply stating that a black screen isn't a difficult level or even a game, it's simply a black screen. How are you supposed to be able to re-spawn if you die - without gear - and expect to start all over with a black screen? If your answer to this is "well, switch server or just stop playing for a few hours" then you might just be a troll.
"If anyone is interested, here is the VOD from my session last night. You will notice that it is grainy and a bit lighter than what you might expect; this is because I increase the gamma in OBS to the maximum possible before washout, to make viewing possible"
So, you admit to gamma hacking to be able to see? I see, maybe you're a troll anyway. The video you linked is far from being as dark as it usually gets in DayZ night time. Just for testing purposes I tried gamma/brightness correction in the GeForce experience overlay, and not even that can make you see the slightest - so I call you out on the video not showing total darkness.
