Mercy, I'm tired of this kind of topics. But ok, let's play this game.
1) Just because the previous games looked like that, doesn't mean that BG3 has to. Compare the series of witchers, each game was very different from each other. It's still the same series.
2) The current soundtrack is great
3) There are many things that can be said about BG 1, but not that it had a good interface.
4) See point 1
6) Volo is in the game. As for the others, most of the characters are long dead.
