And the sky is the limit. 30 years later I'm still waiting for a RPG doing day/night NPC scheduling better than Ultima VII.
It's amazing how much of a break-through that was back then. And I suspect if you were to look at it with a more modern and discerning eye you'd see it was pretty basic... and that something very basic could have been used here to provide a more meaningful effect.
That said, I'm fairly certain that ship has sailed on BG3.
