I love the Witcher series, playing Geralt...
BUT give me a game where I can create my own character and I absolutely will, because in an RPG game where i can be who I want to be then that is the most important thing to me.
So yes, absolutely yes to MORE options for custom characters when it comes to story. I may well play an origin character at some point, but my main play throughs will always be with my character!
The issue is also the whole thing becomes exacerbated when you play multiplayer with people who also want custom characters. Yes we can role play over a mic or whatever but the interaction with the world loses something.
Even Witcher 3 had this quality questionnaire scene asking you how you played events in the previous game in order to know how you impacted the world. Yes I know BG3 isn’t a direct sequel, so that doesn’t work here but my point is that CDPR wanted you to at least define the world in W3 based upon how you played W2 so that it was still “your Geralt”.
