BG3 is a masterpiece. It puts you in a fantasy world were you can believe it is real, with real people you can relate to and understand, with detailed in depth stories, and even the combat, well finally d and d done right. I have not seen a game that is comparable to BG3 yet, with the STUNNING graphics and real world feeling, A quest you can do 5 different ways and each way alters your entire story, WHAT!? not once but all through out the game? And your comparing that to DD2?
How could combats not be Immersion breaking when you can super hero jump all the time, when you can dip your Sword on candles and when you can eat apples (pig heads) as a bonus action ?
Combats are full of totally unreal gimmick that always shout at players : this is a video game.
I disagree with the feeling that this world looks real because the sun is always shining, everything is waiting for you, goblins can't find druids even if they're 200m further etc, etc, etc,... but usually it's ""ok""...
The worst about immersion is definitely combats that looks like a gamey and not serious at all parenthesis in a game that is trying to be serious...
