yes, day/night cycles plus weather effects are a big thing, getting more of that stuff in these new games would be lovely.
I disagree. The problem with day/night cycles in most games is they're much shorter than a real day/night cycle - sometimes as quick as a few hours. Given you do not walk around in the game extremely quickly, this breaks immersion for me. Particularly in some of the Elder Scrolls games I remember playing where you could walk around a city for a very short period of time and all the merchants went home for the night. If you're not engaged in fast travel, game time should proceed identically to RL time.
In contrast, the BG3 "camp" system works in my mind. You start adventuring at dawn, and virtually no one will adventure for 12 straight hours in game without a rest, so the lack of night outside of camp does not break immersion. The teleporting to an identical camp kind of does, but that's a different issue.
Considering the system has short rests that last an hour and 8 hour sleeps (4 if you're an elf) they could easily have fairly long day/night cycles. It doesnt need to match our time because typically the characters are in fact moving faster than we do -because distances between canon places are hugely reduced.
E.g. distance between mournhold and red mountain is 250 miles iirc. But you can travel that distance in not many day/night cycles at all in morrowind.
P.s. my word, yes Pool of Radiance was bad. I remember playing that with my step dad. Lol
