I don't personally consider what Divinity "did before" particularly relevant in this case
You don't think a developers past iterations are relevant to their newest iteration of the same formula?
Strange.
I don't think they should DICTATE their future output, no.
ESPECIALLY when they declared themselves that they are going to delpoy an entirely now one for this game without recycling anything from their previous systems.
Ehh... I don't put much stock in day/night cycles or resting as "World simulation"
I've played WAY too many games where such things existed and they added literally nothing to the world simulation at all,.
No, you didn't. It may be that you played them and you didn't appreciate what they added to the mix, on the other hand.
Flavor, cosmetic variety, immersion, NPC scheduling, varietty of possible encounters or what else.
