For people assuming BG3 feels more like D:OS3 - of course it does. If a product is made by the same group or individual, it always have some things that recognizable as their "style". IRL you can take any artist's pieces of work, they are always have a "personnal style" of painting that diverse one artist from another. For RTS lovers, you can look for example to Frost Giant studio (the Blizzard Veterans) and their new game-in-dev of "Stormgate" - it has A LOT of recognizable things from StarCraft series in artworks and unit design (maybe done for purpose, who knows). Or you can always differ From Software souls-like from any other by many aspects, such as combat for example.
Eh. Let's not mixed up artists (self-expression, high art etc.) from commerial products - which, unfortunately, most games are just that. Marvel be Marvel not because it is their artistic vision, but because charts suggests what sells and what doesn't. What bothers me about BG3 is preciely lack of a coherent artistic vision. It's a product aimed at as wide of an audience as possible, toughing everything and focusing on nothing. Not doing anything interesting as an RPG, not having interesting story to tell. Just something for everyone and for no one.
If FromSoftwere's next game was Devil May Cry or God of War, and they just did Souls-like again - "that's what we do" is not a good defence, is it.
