Since they are marketing it as D&D, that's what I want.
I can understand where you're coming from, but to be fair to Larian, they're not exactly marketing this as a pure D&D experience. Here's what the "About" text says on the Steam store page for BG3:
Gather your party, and return to the Forgotten Realms in a tale of fellowship and betrayal, sacrifice and survival, and the lure of absolute power.
Mysterious abilities are awakening inside you, drawn from a Mind Flayer parasite planted in your brain. Resist, and turn darkness against itself. Or embrace corruption, and become ultimate evil.
From the creators of Divinity: Original Sin 2 comes a next-generation RPG, set in the world of Dungeons and Dragons.
Notice the way they separated "next-generation RPG" from "the World of Dungeons and Dragons," a heavy hint that "next-generation" won't be exactly the 5e tabletop experience, and they're only using the Forgotten Realms as a setting, not a literal translation. I'll bet it took the Larian marketing department a few days to come up with that exact text.
