Simply put, I don't want another Infinity Engine game.
As someone who enjoys D&D, this is so far the best translation of the tabletop game to the PC. There's some liberties that were taken with the rules, but none of them really detract from the experience. People complain about the disengage as a bonus action, but if RAW disengage mechanics were kept, every fight would involve half the party being locked down the entire fight because they're spending every turn running away from stuff. The terrain and barrel mechanics were carried over from Divinity:OS, which is a questionable decision, but only really an issue if you can't stop yourself from exploiting them. With so many Infinity Engine successors, I don't get why people are so desperate to have this game be a glorified small-party RTS game(rtwp), especially when they've been released constantly and never reached the success of Larian's last two games, which shows that it really is just a small, overly vocal minority that wants a mechanically similar sequel to that type of game..
Yea, maybe the game doesn't have the same mechanics as the original Baldur's Gate games, but I'm not looking for that. There's been already been 5 of those(and their enhanced editions), and tons of isometric RPG's that follow in the footsteps of the Infinity Engine games, with Pillars of Eternity 1 & 2, Tides of Numera, Tyranny, Pathfinder:Kingmaker, Underrail, and countless others currently in development, but I don't think it was ever the intention of Larian or WoTC to create yet another one.
What we're getting is the closest representation of the table top experience of D&D(as opposed to the RTS engine it was shoehorned into 22 years ago) with the current ruleset. Baldur's Gate is older than the first video games that depicted it, and just because Baldur's Gate 3 doesn't play the same as the first two doesn't make it any less of a Baldur's Gate game.
