Video games are not PnP games. If "recreating the PnP experience" is what this game is about, then it should be advertised as a PnP simulator because calling it a video game is false advertising.
You are correct in that video games are not PnP games. But that doesn't add much to the conversation. To call BG3 a 'PnP simulator' wouldn't be accurate either. Maybe a video game version of PnP? A video game seeking to recreate the PnP experience? No matter how you look at it, it's a video game. But there is nothing about "video game" that is necessarily, or even remotely, at odds with turn based play.
