I think that all aspects of sound design are important in a game. Vampire the Masquerade Bloodlines, which is my favorite game of all time, has a brilliant soundtrack and amazing voice acting where it counts. The characters in Vampire are some of the most charismatic out of any game I've ever played, and it's in no small part due to voice acting. Sure, the game failed at launch, but it still has a strong cult following. The music in BG3 is great, and the acting has been very entertaining so far. I have high hopes for the finished product.
