IIRC, the reasoning is that there are already more than enough dark locations in the game; basically almost everything other than the open world.
If nights were as long as daytime, players would be most of the time in the dark.
Having said that... I think we could use an extra hour or so of nighttime.
Good for one of the vampires' passives, too.
Is it just me or do the nights feel non existent in this game. It feels like it’s always day time and it really bugs me. I prefer the night time, and wish they were as along as the day cycles. What do y’all think?
