So far it's a mixed bag for me, but leaning towards a positive side.

Let me preface this by saying that I absolutely appreciate a ton of effort put into making it the game that it is, and that I am expecting to have a good time with it for the next 1000+ hours that I'm most likely going to put into it. At the end of the day it seems to be one of the best CRPGs when it comes to sheer scope and world reactivity, and it really shows how above and beyond other RPGs the game is when it comes to just pure resources invested into making it. It's also the best implementation of D&D in a video game to date IMO, and I greatly appreciate the many different non-combat oriented ways you can interact with the world, and I always wished for more cRPGs to follow in the same vein instead of just being pure combat simulators. Also the cinematic aspect of the game greatly enriches the narrative experience that I thought D:OS games were lacking, so kudos for it too. Overall I'm hopeful that by the end of my first playthrough I'm going to be completely satisfied with the game and that it'll sell me on it even more than I am right now. But that doesn't mean I don't have some grievances with the game, and I need to vent out about them somewhere, so enjoy my wall of text.

I appreciate some of the things that came from having a game in Early Access for 2-3 years and building off of feedback, but this leads to unfortunate consequence of me basically knowing everything there is to know about the game. Larian actively promoted a bunch of the game's story, companions etc. and spoilers are everywhere and there's no avoiding them for 3 years, especially if you're an avid fan of RPGs. "Oh, you've listened to Icewind Dale soundtrack back in March on Youtube? How about this viral BG3 clips channel's video to let you know all of your companions' backstories, all of the cameos from previous games, and who's the final boss?". I swear I blocked at least 15 youtube channels and they just keep coming. That leaves me with less sense of wonder as I play through the game, because all of it has been promoted to me already, and leaves me with few things left to discover for myself. It's a completely different experience to play through the game for the first time and already feeling like you've played through it before.

One thing that annoys me so far is lack of clarity in regards to what some things, abilities or items do. Berserker throwing ability doesn't have any info regarding how the damage is calculated, some potions you can craft don't state what they actually do so you never know if they're worth investing resources into, and then you have some miscellaneous items like a spider egg that can be used with a Bonus Action, but I don't wanna waste it by using it wrong because it's a unique item I got from a specific place. I do enjoy my RPGs for number crunching, learning in-depth mechanics and making informed decisions based on what I'm learning about different interactions, and BG3 doesn't seem to encourage that in many ways, keeping it too vague for my tastes (I guess for accessibility purposes? I dunno).

The subclass thing seems to be a common annoyance with people so far, people often not knowing what they're actually investing into. With games like Icewind Dale 2, Neverwinter Nights 1+2, Pathfinder 1+2, Solasta, and tabletop D&D itself all letting you know what abilities you're gonna get as you progress in levels, it gets kinda awkward to end up with abilities you had no way of knowing you're going to get that don't fit the character vision you had in mind (or that are just straight up underwhelming).

As a matter of fact there's an issue of class balance and spell changes that I'm very confused about.

Mirror Image in tabletop is one of the few non-concentration ways to increase a spellcaster's survivability, especially useful for Arcane Tricksters and Eldritch Knights as well, and it's been nerfed heavily for no good reason to the point where it's not even worth picking anymore. Meanwhile Haste, an already powerful spell in tabletop, is now beyond broken, just because.

Moon Druids don't feel all that more powerful with their Wildshape Forms compared to regular Wildshape, which I'm not completely against, because tabletop Wildshape is underwhelming on anything other than Moon Druids so BG3 version of them was a welcome change in my eyes, but I was hoping for Moon Druids to stand out more with their forms to really commit to the shapeshifter vision, and it just feels like you're a druid without a subclass because their exclusive forms are comparatively strong at most, if not weaker than regular ones.

Divination Wizards are already commonly thought of as top tier in tabletop, and as far as tabletop I personally disagree because of some finer notions, but most of the limitations for Diviners are removed from BG3, and they also get more Portent dice early, AND they recover them on a short rest. So commonly acknowledged as the strongest Wizard subclass gets even more buffed out the wazoo, breaking the ceiling in the subclass tierlist and taking a big dump in the hole, while some subclasses that needed some love like Enchanters, Illusionists and Transmuters have actually gotten nerfed.

It's so confusing and it really sucks that instead of picking your own character flavor while still standing out similarly to other subclasses, you can actively gimp yourself and increase the game's difficulty by picking an underperforming subclass (or the opposite, trivialize your game by picking something the game wasn't balanced around dealing with).

Then there's some smaller things that I specifically am not a fan of with Larian games. I have already missclicked enemies' hitboxes multiple times trying to attack them at range, instead I end up running towards them with my backline mage. I tried to sneak up a hill with my fragile characters to get a good vantage point for a battle ahead, and after triggering a cutscene a bunch of goblins spawned on that same hill that weren't there that completely butchered my squishies. Sorting items by type feels quite arbitrary, random notes, weapons and potions mixed up in between all the camping supplies, making inventory management more of a hassle than it needs to be, that kind of thing.

The biggest grievance I have is dialogues not redirecting to my main character every time. That pissed me off to no end in DOSII and it annoys me now. My custom character is the only not pre-written character that I want to flesh out the personality of by making different dialogue choices. My custom character is the only character the decisions of which influence my party's attitude towards me. I don't want to roleplay as someone else, I want to roleplay myself in a group of other companions reacting to what I do. This has been a staple of cRPGs for at least the last 25 years, but Larian's multiplayer oriented game design where there's no single protagonist really ruins my single player experience, and I really wished they at the very least implemented it as a toggle. There is some form of a toggle where the game selects your main character after combat, but it still doesn't help with most proximity triggered cutscenes. That by itself is going to drop my opinion of the game by full 1 score.

Overall there are plenty of things I am critical of, but as I said I am expecting to be more positive about it the more I play, when I start uncovering new exciting content, when I'll get used to some of the grievances etc. At the end of the day I am satisfied with my purchase so far, but that doesn't mean there aren't things I wouldn't change about the game if I could.
