Yeah sorry OP I can't agree on this.

There will always be similarities because each game, book, etc... takes inspiration from the same sources. Witches in huts in dark forests is not a W3 thing. Yes, the HAGS (plural) from Witcher 3 were very memorable and like most things in the W3, just brilliantly written, but the are not unique. Same with Bards following you around and being annoying. Plus you don't have to save Volo you know!

Regardless, I am sure any "closeness" is flattery and the game is certainly in no way failing as a result. There are many things wrong with BG3, but having similarities to Witcher 3 or NWN is not one of them.
