Well, it's definitely early access. Quite a few bugs in the animation.
Beyond that, the game looks and feels incredible. It really captures the tone of the original series nicely and I wasn't expecting that. Based off a few of the trailers, I thought it looked more like Dragon Age, but I love what I've experienced so far.
It captures the tone of Baldur's Gate rather well, I'd say. It does a pretty good interpretation of the drab, weary world of the first couple games quite nicely. Note that "drab" isn't exactly an insult here. Baldur's Gate to me is a much less vibrant, albeit colorful world than Divinity and is a bit less "lively" and has more of a depressed tone across the board. I thought that would be lost-in-translation through another developer's lense, but it's really not.
The gameplay definitely uses Divinity as a base, but it doesn't feel like I'm playing Divinity at all, really. It still feels unique to the game itself. I'm not really a DnD player, but it didn't feel so alien to me. There are more similarities to the original series than I think people might realize.
Of course, I also played the OG unpatched BG1 CD and I doubt anything could feel as terrible as that.
People just may have a hard-time coming to grips that there's a sizeable luck factor with the DnD system the games are based off of. Anyone who's unfamiliar won't consider options they have to offset that.
