I very much hope this individual turns out to be correct, and that other RPG developers don't try to copy BG3. Since BG3 is a piss-poor game to me, the last thing I want is for BG3 clones to start popping up.
And to be clear, what I want in an RPG is very much great writing, deep and immersive story, strong character development, branching dialog, extensive character customization and reactivity, etc. But I reject the notion that we're getting any of this from BG3 in a truly meaningful and non-superficial way.
