People need to start realizing that they like the thing they always liked for a reason, because its that thing. you cannot simply replicate it and get the same result. You cannot recapture the magic of old, you can only try to create something new.
Finally a post of yours that makes sense to me and with which I agree. They want to create something new, and that's great. So why not call it something new as well? Why call it BG3?
