D&D is balanced largely around the question of resource management, namely day&night cycle.
When playing, this is handled by the DM along with the players through narration. But in a game like BG3, it becomes a little more difficult.
One issue I encountered while playing was the ever present feeling of cheating the game anytime I pressed the "rest" button. Because yes, resting in D&D is ALSO a resource to be managed.
And so, since I can rest anytime I want, reset my spells after every fight, engage every ambush with full hp with no cost whatsoever and succeed this way much more often... Well I feel like I deserve none of these successes. "Well, then, just rest less often, you absolute inane QQ machine", you'll tell me (in more gentle words I hope). Your advice would be sane. But what do I gain by not resting? And what interval is the right one? Who decides? I have no DM to turn to, and the game gives me no obligation, no limitation, nothing to aim for. I just limped away from a fight against a horde of goblins, closed the makeshift door behind me and blew off the torches best I could. Now, surely, the goblins are looking inside every room to find me. But the magic button teleports me in a magical forest, where my magic campsite awaits, with weirdly uncomfortable-looking sleeping bags. Right now, the campsite feels like it's nothing short of a level 6 "Druid Grove" spell or a level 7 "Mordenkainen Magnificent Mansion" spell. Only it's FAR better, as it's completely free and doesn't require casting time or anything.
Anyway, I'm belaboring the point. Bottom line is: it feels weird to not have days and nights. It causes me to second guess every single spellcast, leads me to feel like I don't deserve my successes and kinda breaks the spell&rest system a little bit. As it is, it's a poor way of managing resources.
I gain the sense of knowing that I'm playing the game the way I want. I was thinking that this was going to be focused on the lack of night for actual gameplay, instead of just another "but Long Resting is bad" thread. The immediate solution to the problem is to just not do it. It's what I do, and, in fact, I was afraid to do it initially, because time bomb in my head. Even after events play out, I refrain from doing it, not because I feel like it's exploitive or anything, but simply because that's my approach to a lot of optional things, if I don't feel like it's something I have to do, I don't do it. I carry lots of food too. Do I use it in combat? Nope. But I will use it after. Why? Because I can't see stopping in the middle of a fight to "make a sandwich". It's also why I don't change armor in combat, and why I don't loot during combat.
