What is immersive in an RPG isn't so much that as I travel it suddenly turns to night. Actually, games that do that are very unimmersive to me. I don't like RPGs that have sped up time.
I’m definitely with you there. In fact, I’m not sure I’ve played a game that has done day/night cycles really well, though I’ve played some that have done a few nice things with them. Athkatla at night in BG2 being one of the best examples.
I think if a day/night cycle were designed into a game from the ground up, it could potentially be great. But I suspect half-arsing one would be worse than not having one at all, which is why it’s not something I’d agitate for in BG3 at this point.
But I do hope that Larian will find a convincing way to have some missions take place at night later on. We’ve seen with the swamp that they can do different things with the same map if they want to, so it looks as though they could have night fall if it were significant to a quest.
(I’d be all for some drow sunlight sensitivity, though, even if this were just a disadvantage to perception/hit when standing in full light outside, and even if my drow couldn’t do things at night as would be more sensible.)
