problem is having a "realistic" dark night would quickly becomes annoying the same way murky waters are X3
Not really, as I dont normally travel during the nights any, but if I got caught to far away from a town to make if before sundown this would just mean that the dangers increase traveling by night as you cant see that far ahead to avoid enemies, this would actually enhance traveling at night alot more.
The main roads leading to towns/cities could be lit by lanterns, but in the middle of nowhere then it should be very dark
And with regards to your comparison with Murky water, if murky water was not murky for 12 hours of the day it would have been sooooo less annoying.......Unrealistic........but less anoying lol
