Can't remember since it's so long ago, but I think Divine Divinity 1 also didn't have one.
Duuuuude it does. Divine Divinity - my very first cRPG that introduced me to both the genre and Larian - does have D/N cycle. I can't even begin to describe to you what it felt like every time when it got dark I would teleport back to the Blue Boar Inn, next to the pumpkins and the chicken houses, entered the inn through the back, said hi to Lanilor as I passed through his room, then grabbed some chicken drumsticks and beer from the inn owner, hanging for a bit before resting till next morning, all the while listening to the hauntingly beautiful music. The track that started right after the teleporting would usually be The Song of the Wind, then it changed to the lively Drunk with Dwarven Mirth. These memories are so vivid it's almost to the point of being painful every time I recall them.
Yeah, the point being, I don't know what others play games for, but I play precisely to search for such powerful memories and feelings. It's cRPG and immersion is a big deal, and the D/N cycle is a big part of it. Wish I could be more eloquent here but eh.
