I hate beating a dead horse, by my personal concern is Larian’s coop-centric design. Due to personal preferences I don’t mind at all BG3 being turn-based, but that is not that I didn’t like in D:OS2. I didn’t like the quest design, map design, narrative design, weak companions and constant feeling like I am playing a multiplayer game by myself. One can easily point out to similarities between D:OS2 and BG3, like a origins, which for now I don’t like as a concept.
That said, gameplay they showed did raise my interest, and does seem like a promising improvement.
