To be honest I find day/night cycles fairly unimmersive just because the days and nights pass in the span of minutes while I've been watching my character move and talk in real time the whole time.
I prefer this "the questing day is as long as you make it" strategy because I can imagine my characters being worn out after a couple big fights and wanting to rest the rest of the day.
This sounds a pretty arbitrary thing to complain about, given that most games do day/night cycles at different ratios (i.e. a full cycle may last 2, 4, 6 hours or more...) and in some cases it's even a customizable option.
Also, NO, definitely not a fan of "make believe" mechanics where you decide in your head what matters and what not and there are hardly any real in-game consequences.
