The game will have, according to Swen, several story elements directly linking BG3 to the past games. That’s pretty concrete.
Not sure it's really concrete until we see what he's talking about. I'll write it again... but Bhaal is not only what defined BG... (+ That's related to the FR... we're turning round if u don't keep what was said before in mind).
I saw that, but asking how this game should feel like its predecessors without permitting mention of most of the things that defined those games (the story, the setting, the rules) seems to me a bit of a rigged game.
Artistically both games are a match as much as possible, seeing BG1 and 2 were low resolution pixel games.
