And there is no similarity with that identity, in style, gameplay, tone, environment, in Larian's shown "BG3".
Other BG1+2 fans disagree with your opinion on that.
But with what argument? Yes Larian is good, BG3 is possibly a super fun game BUT not a single BG fan can say that this was Baldurs Gate.
You have to devide it. People who like the gameplay anyways (which is fine) and people who wants more baldurs gate. Saying that this was baldurs gate style, atmosphere or whatever is an utter lie.
If larian would say "Calm down people, this was just a demo out of dos2 assets to show you the direction we're going" fine. But don't tell people that this is a baldurs gate game.
