Again, for the umpteenth time, you literally haven't seen any of the game beyond an intro area that teaches you about the game and it's basic mechanics. You haven't seen the darker and grittier parts of the game. You haven't seen 99% of the world and the feel of it. You haven't seen the areas, like Baldur's Gate, that may actually align more to what you are expecting to see. You haven't seen the people and stories that actually connect this game and storyline to BG1 and 2. Swen said he literally played through both BG1 and 2 in preparation for making this game.
All you complainers literally haven't seen anything to complain about yet when it comes to the look and feel of the game, the story, etc. The only complaints you have a leg to stand on about are the reduced party size (which I agree, I'd like it to be at least 6) and that's about it. Everything has a 'realistic' look compared to the 2D, lower resolution of the first games.
Apart from the obvious mechanical differences in gameplay the fact that it looks so undeniably similar to DOS in visual terms can be gleaned from what we've seen so far, and that alone is very annoying. I don't have any expectations that it would remain in a 20-year graphical stasis necessitated by foolhardy allegiance to a certain outdated aesthetic but it should definitely have its own visual identity rather than piggybacking on that of another.
The main thing I can tell from what I've seen so far, though, is that I don't like it.
Anyway I'm done with this debate as I've registered my discontent and I shall merely vote with my wallet when the time comes, as will we all. I hope it turns out to be great in the end and the concerns fall away in the face of RPG excellence, but I shall not be optimistic.
