So some things... I am glad the OP is tuning the responses so they aren't thread locking. The conversations and points brought up on the game are worth discussing and hearing. My biggest contention is in expecting Early Access to = Release Candidate. This is just a falsity. Early Access is just a marketing term. Literally every broadcast about the state of the game, before any purchase is made, declares this unfinished, full of bugs, etc. So expecting more than a buggy experience is not the best way to approach the purchase into EA. EA is meant to get the die hard feedback people into the action before the product goes gold. To get feedback from the consumers, waaaay before release to the general public. The ONLY reason this games EA is as popular as it is, is due to the timeline for the franchise. BG is a much loved franchise (in a much loved system) and fans of that clamor for new content/products. And they pretty much all have something to add to make the product more to their liking.
Ok, so that is done. Now to the meat and potatoes of the OP's feedback and what I am seeing/thinking about it.
Most of the bugs are really easy to fix and should be fixed before gold. That is purchase blocking issues. No brainer there. Good for at least getting visibility to them.
The most interesting of them is prone-locking. I can imagine it is a way to play, however, I do not think it is 100% exploitable. Each digit on a d20 is 5%, so given all that, there should be a 95% exploitable scenario if you only fail to keep a target prone with their critical success/save. Gives me an idea to try one though
Not gonna lie, the first annoying issue in the letdowns thread, made me laugh. Then I watched the video. Laughed even more. I mean, it is comical to see the constant character clicks after trying to not break the party by spamming spacebar to get out of the convo. With that said though, it unfortunately looks a lot like user issues. I don't have a beefier machine and I rarely click where I don't want a party member to go. Sneaking helps with giving a specific reticle and line to it to make things more obvious/visible. I know from pen and paper, that I am not supposed to be able to share a space, so I don't try to click in the space in front of a toe, knowing that the space the object occupies is more than 1 pixel around the feet.
Most of the other annoyances are simple bugs and should get fixed.
The bugs section: yeah, same as above. Bugs be bugs and they get fixed only if the players report them. I say players because we have no idea what internal QA has on their plate.
Fog of war: The game has some of that by removing the actors from the scene beyond your visible range and the minimap shows your visible range. I don't know if you know this, but you can't move the camera beyond that point (on its Y axis). Or if you can, it is not by far. So you can't really explore the entire map from the entrance. Maybe if there was some indication of a camera barrier, it would help indicate that feature in play. Like a bubble? Or lines indicating the max the camera can move?
I don't know what surprises are spoiled when actors/objects not seen yet are not shown in the distant areas as you pan the camera around.
I do think some conversations should have an escape option. Like ones that have been repeated, or ones where no plot/character influence can be had.
Most of the other suggestions are good and sound like incoming features/something to get done before gold/required for gold.
Most doors are heavily resistant to pierce damage as a type. So it should (and is) better to bash them in with a hammer than shooting arrows.
The other thread is more suggestion based and hits on many of the same heads and themes. Glad they are there, since it definitely highlights a common feature set, every crpg should have.
And, you also know why they locked the threads. So winner, winner, posting dinner.
