I would love to see a day-night cycle too, one of the best things about pathfinder kingmaker for me was the fact the game had even snowfall with the coming of winter. Doubt that will be something in bg3, but a day-night cycle would add quite a bit of mood to the game, I want to see Baldurs gate as a city at night! Sneaking with current mechanics could potentially be too strong at night though, I am not sure.
