what does that even mean "teach you how D&D is meant to be played"? As if I need to be taught? Baldur's Gate is a computer RPG based on D&D. It was never meant or designed to be an accurate translation of PnP rules.
Even Larian is making exceptional changes to D&D to make it work as a video game. Which is the same reason Bioware went with RTwP, to harness the video game part of the product.
Wizards is making a HUGE error in trying to push BG3 as an entry to PnP D&D.
Of course BG3 will be a success, though. It already bought its success through marketing.
