I think the problem in our case is (and I can't believe I go back to it) is with the name Baldur's gate 3. If this was a divinity game, I feel like there were other expectations associated with the name Baldur's gate that aren't associated with divinity.
Of course it doesn't matter if there is no response whatsoever from Larian
This is a rather broad statement that I'd have to disagree with. It [at least appears to] makes the assumption that complaints are focused at it being a Baldur's Gate game rather than a Divinity sequel, when this isn't even the point of contention for the topic. Complaints are aimed at lack of added content and progress in EA, lack of communication and when there is communication, lack of meaningful communication.
There was a survey done early into the EA which showed only half of the participants on Reddit had even played Baldur's Gate, while 70% here reported the same. Personally, I've never played Baldur's Gate and I'd have no interest in it because I don't like RTwP. I'm here because of Divinity and turn-based RPG and not Baldur's Gate for instance. I have a difficult time believing the complaints which have nothing to do with the name or even the genre (this could be an FPS shooter and it wouldn't matter) are because it's Baldur's Gate and not Divinity.
We're eight months into EA now with basically nothing but a Druid class, some minor tweaks to companions and some comments regarding analytics that some are arguing seem to be willful misrepresentation of data. Meanwhile comparisons can be incredibly effective and important, especially because both are top-down RPG adaptations of PnP rulesets, both are being developed under Covid, both are in early access, etc. The only real differences being in developer size, funding (one is a kickstarter and the other is on the tail end of a successful release and backed by WotC) and scope (25 classes and Mythic paths vs 12 classes). Sadly, the one with seemingly more against it is the one that has been communicating and delivering content.
Meh, that's it for me on the subject though. I'm just massively disappointed in the prospect of an EA which is supposedly geared at getting feedback and testing and has not taken advantage of it or lived up to it. I'm rather concerned with the final release when there's still other classes and multiclassing to test, as well as plenty of other content.
