I loved DOS1 and 2 and have played DnD 2nd, 3rd and 5th editions not to mention loved Neverwinter Nights 1 and 2 (I didn't enjoy much in terms of BG1/2 or planescape:torment).
So far I have played BG3 and I just keep thinking it doesn't feel like DnD.
The fights are focused on us fighting hordes of magically-charged goblins who, unlike actual dnd monsters, are full of environment-interacting utility and spells they have no business having access too. I mean, in DnD the average player at 2nd level will have 20hp. The average CR2 Ogre, designed for a group of players to fight, has 75. Allowing the Ogre to cast sleep with the same strength as a player is utter MADNESS - it really flies in the face of common sense.
Action economy is a big deal in 5th edition, it's all about maximizing the ONE action and ONE bonus action you get... except Thief Rogues get 2 bonus actions, because Larian doesn't appreciate things properly in not having us constantly pitted against more mobs than we should face.
It's also written in the rules you can't cast cure wounds and healing word in a single round... but no, Larian don't care about that rule!
The programmer for Sneak attack spent no time reading up on it, because not only can it be applied once per turn, but it can be applied after you hit with an OFFHAND attack.
I don't understand why Larian felt it unnecessary to capture the essence of 5th edition just to spearhead their desire for environment interaction... stop removing the fun of DnD from this game and start understanding how little things like potions as a bonus are fine, but hide FAILING TO GIVE ME ADVANTAGE FOR SNEAK ATTACK is not... sheesh.
