I think the thread raises valid points and Larian may or may not discuss it:
(1) The graphics and general presentation of the game are, right now, very good. I don't think anyone would disagree with that (2) It's of course a far cry from pathfinder kingmaker or pathfinder wrath of the righteous, which many people argue is closer to BG1/2, in mechanics, world and storytelling (3) Some people are rightfully pointing out that they want their Elves, Drow, Tieflings to be rare, enigmatic and special. By going overboard and presenting Tieflings, Drow, Elves, Githyanki, Illithids, Dragons, high end magic etc. as 'everyday' occurence, they essentially become boring. (4) Having a few "special" companions that are vampires, have a demonic pact, slept with the god of magic etc. is fine, but again, they can only shine if they are put in contrast with "normal" companions. (5) The game is centered on the player, but the player seems to be the least cool/important. In BG1/BG2 the player was the spawn of Bhaal, which resulted in a whole lot of comments by companions, romances etc. Right now it seems the player is the most normal of the bunch. (6) There is apparently a big change from D&D 3.5 lore to 5 lore, which confuses people who played BG1/2. Their beloved evil, supremacist Drow are suddenly the same as Humans with silver hair, long lived, spiritual Elves are just the same as Humans, only prettier, infernal Tieflings are the same as Humans with horns and glowing eyes. (7) Fantasy and science fiction is popular because people actually love to discuss philosophical questions in these stories. How would a long lived species like Elves behave? How would evil Drow organize their society? I'm not asking for Baldur's Gate 3 to be a PhD thesis but a bit of Jules Verne would be cool.
