Games Larian makes are much closer to DnD tabletop than other crpgs are, even before BG3, that is all Larian has been making. Crpg games that try to be as close to the tabletop experience as they can.
Bg3 will feel closer to tabletop and than bg1 or 2 ever did by the time it is finished, unless they decide to stray further from it from now on, instead of closer.
Some rule changes need to be reverted, such as sneak as a bonus action, features need to be added, such as exhaustion and risk to resting, but that is just about it.
