Joking aside, I am not convinced adapting BG3 is a good idea. It is not a game with strong narrative drive - it is player choice and system driven, and once you take that out, I think you will find that what remains isn’t particularly compelling. So doing a project like that would be pretty much making something out of scratch just casting actors because they stared in a video game together. I am not sure how strong of a pitch it is.
I think The Last of Us worked because the game is pretty much written like a movie/TV show anyway. But yeah; adapting a big sprawling RPG full of choice and characters is far less feasible. The best thing I think is just to tell new stories set in that world, and you can maybe have one or two familiar faces pop up now and then.
