Like it or not, Larian makes rated R Disney games. Not sure I would call that <dark fantasy>.

Alright then, BG3 is a Dark fantasy rated R Disney game. lol.
Calling it <dark fantasy> Doesn't change a thing in the mood and art style Larian adopted. Same as calling it <Baldur's gate> does not auto-make it a Baldur's gate game in terms of mood, immersion and art style.
