The world of BG3 feels very DOS because it quite frankly is, static and inorganic. The combat and lore are very different becasue they D&D'd that bitch ergo good. The combat and spells etc. are D&D with certain caveats but a pretty accurate conversion if I am being honest.
The world is as much a part of the gameplay as the combat mechanics. They go together like crackers and cheese. DOS world with D&D combat is more like Whiskey and orange Juice, yeah it gets the job done and gives you a buzz but it tastes bloody awful.
To be honest, I was shocked to learn of the lack of day/night cycle; this "innovation" was present as far back as Baldur's Gate (with its comparatively "primitive" graphics) for crying out loud.
