Why is Larian so diffrent from other studios?

Ok by now I think its pretty clear that BG3 is one of the best rpgs in at least the last 10 years. So what is your opinion, why did they made such an effort to create a truly great game and that they are still making big patches to fix things even tho their game is already a success. I know thats is bizarre to ask, "hey why did you make such a good game" but sadly the reality is that in the last 10 years 90% of game studios are putting out really bad or mediocre, cash grabing games with no repsect for the players, so a great game like this is an exception ( especially in triple A segment ). What is that magic that Larian has and a lot of others are missing?
