Its no secret that a lot of players want a day/night cycle in BG3, me included. Sadly its also no secret that Larian seems to be opposed to this idea. This thread is not supposed to repeat the arguments for a d/n cycle, since there are already multiple other threads that adress this.

In this thread I would like to suggest introducing exhaustion rules (as detailed in the PHB) to BG3 to 'mimic' time progression, since an acutal d/n cycle is unlikely to happen. The idea is to give a character one level of exhaustion for completing a set numnber of encounters or fights. This would not immediately force you to rest, but make it harder to fight on as you gain more levels of exhaustion by progressing the story, and it would give the impression of passing time in the sense that you're exhausted after a long day of exploration and combat.

What do you people think of this idea?
