And especially when you factor in that fans of the FR setting (even if they constitute only a minority of BG3 fans) are that much more likely to mirror the setting's favoring of the good side over the evil side.
Well, I have never played the first 2 BG but I love the FR setting, especially many of the neutral and evil characters.

Besides, there has to be something to do for the good characters, many of who seem really shallow and predictable.
