I also compared the sales of Larian's last popular game release Divinity OS II at just over 1 million, with the number of people currently playing 5e D&D too, which is 14 million. That's not even including people currently playing other editions of D&D. My point was, 5e D&D has a bigger player base than this game will. So I am suspicious that the decision to deviate so much from the 5e core rules will actually generate larger appeal and sales than just staying faithful to 5e and attracting that audience, along with people not familiar with 5e who enjoy a more balanced game.
The problem is that not all DnD players play video games. It's like focusing on the board game audience when you're creating a video game. Hmm
