As you said, you think it is better to compare it to DOS than BG 1 or 2.
That, specifically, is a problem for me. I am here to play BG, not DOS.
Was about to say that. This is a huge problem. The game appears as if it was D:OS that tries to be DA. Set in Faerun and with 5e rules. And titled BG3 for some reason. Location and some story links aren't enough.
Yup. That's my perception of the game as well. I would just add that it fails in trying to be DA, but that's about it.
The more time I've spent with BG3 the bigger the disappointment became. At first I bought into the classes and 5e surface, but the feeling of the game has nothing to do with BG. Even the 5e ruleset that is in there in huge parts gets watered down in the most obvious and significant parts to see the DOS mentality underneath everything (not talking about UI and some old engine related quirks, I don't care about these placeholders one bit). Honestly I after DOS2 I would never had both any other DOS-game for full price, even less wasted time on a EA. I was expecting a BG3 game as they kept harping about how much they care about making it a 5e experience.
Sadly they have also completely failed making the characters feel like D&D characters. With storys far bigger than their level, enemies that should be far too potent for level 1 characters, arch druids on level 5,.... non of these would bother me in a different type of game. I actually prefer games that don't use a level mechanic like D&D. But in D&D its different. Levels are not mentioned in the story, but you simply feel them in everything. BG3 has none of it. They are meaningless beyond gameplay itself and it feels off. A party of 4 level 4 characters killing a beholder? Really?
And this negligence in design is too obvious when you look at your origin characters. There is no elegance in their writting or background story. Even the tadpole as explenation for them not having their full powers is grotesque lazy. Do I need a party of 4 Eders? No, but at the same time I am a 100% the BG3 team couldn't pull of even one. For all the shit I might give PoE, they had fitting companions - non too big, slowly growing to the challenges, giving insights into the world with their own background, never overwhelming the player character. A good character is more often than not memorable because of their behavior and quirks, not the big special background story. Also all Larian characters being the actual main characters it leaves no room for a custom character.
Now if the game was just about origin characters and the custom character was advertised as second thought/additional opion I would be fine with it. If that's the game they want to create, I won't object. But they didn't and instead assured us that the custom character is important and will be a full experience. They are not and the game overall is not was they said it would be. At least to me, so feel free to disagree.
