Larian Studios Forums Baldur's Gate III Baldur's Gate III - Suggestions & Feedback The issue with day/night cycle and how it can be addressed.

I don't get Larians position on this.
Having cycles and weather doesn't necessarily means you need a complete <simulated world> as they call it. I wouldn't call BG2 a simulated world, yet it takes care of day/night cycle quite simply.
They are WAY overthinking the issue.

BTW playing poe2 deadfire right now, the dynamic weather/ time cycles in that game as so great....(a bit too fast though, slowed down with a mod). Adopting these systems makes that much difference to your world's atmosphere.
