It would be nice to have some camping but it won't be in this game. Hopefully in D:OS 3 if this game does well and they are feeling ambitious enough to add a day/night cycle because that won't be easy given the current complexity already. (But it would be so worth it!)
As a HUGE fan of the Ultima games, I was among the firsts to complain about the lack of a day/night circle in the first game (a future that was announced during the KS campaing, to make things worse).
Then, I realized that there is at least one technical issue that prevents Larians to add this feature to the game: the co-op campaign. Specifically, the chance for one player to get involved in a turn based combat while the other(s) is wandering the world in real time.
With a day/night circle in place, and the aforementioned possibility, you will have absolutely moronic scenarios where several days pass while one player is stuck in combat.
