Like someone else already said, I think RTwP is an outdated system that served it's purpose by trying to do something that Turn Based simply does better.

As someone who plays D&D every week and has played BG 1 and 2 extensively, I don't feel as though RTwP reflects D&D at all. I was excited for BG3 precisely because of Turn Based gameplay, and if it were taken out I probably wouldn't play it. Having said that, I don't think Turn Based would be removed because of a point I've already made - D&D by its very nature is turn based and this game currently does a brilliant job at it.
