You'll probably pleased Larian's fanbase, you'll probably please D&D fanbase... But I still never see any "only" BG video game fan that is happy wherever I read discussions about BG3.
I think Larian is very happy if they can please Larian and DnD fans. They can definitely live with having some angry BG lovers.
Of course they will, but it could be so easy to pleased everyone calling this game Baldur's Gate : The divinityve edition. I like the suggestion.
