BG3 has nothing to do with Skyrim. The gameplay has nothing to do with it. The story has nothing to do with it either. BG3 exists because of BG1 and BG2. You would know that if you’ve ever played one of those game. But you didn’t because you are to young to know shit. As a matter of fact, every Larian’s game exists because of Baldur’s gate. The world didn’t begin the day you grab your first controller you know?
Now, if we stop talking about gameplay and talk about money like you did, BG3 never had to wait for Skyrim to be a success, as there were tremendously successful games before Skyrim already.
Keep repeating yourself if you like, it won’t change how wrong you are.
