The studio I most hope will be re-evaluating their life choices should BG3 turn out to be the success is BioWare, for whom I think BG3 gives a kind of alternative vision that shows you don't need to abandon interesting and complex party-based combat and a high degree of customisation of your player character just in order to make enough money to tell an immersive story with high quality animation and voice acting. Of course, I take people's points that BioWare's position in the EA stable is restrictive, and both they and EA would also understandably concerned that there's a unique combination of factors that mean that even a BG3-clone couldn't be pulled off by someone else, but I hope they're at least considering whether they might have some lessons to learn from Larian.
The problem with that is that BioWare of today is not even remotely what it was back then or even they created Dragon Age: Origins.
It's a shame. I remember playing Dragon Age: Origins and thinking it would drastically change the way video games approach RPGs in regards to backgrounds for player characters. Then no one ever followed up on it.
