I don't know I love Larian but I think they changed a lot from 5e that they really did not have to change. I play 5e on a regular basis and it's very beginner friendly. People picking up the game I don't think would have issues learning the system even if they dont D&D. BG 1 and 2 were pretty successful and used AD&D's confusing ass system to the tee and at the end of the day people loved it.
