This is an amazing RPG but the game processes from a master piece of story telling and plot development, to progressively go down hill with the last bit being a mad rush to the bottom.
Is this really true though?
I've watched Larian drop the ball on endings in multiple games now. My diagnosis is actually a bit different. From where I'm standing, problems with the main plot begin *right away.* I don't actually think that starting the game off with an epic chase on an alien spaceship, multiple dragons, teleporting to hell, etc. is a very good way to start the game, in fact I think it is very bad. It's a longstanding Larian tendency in writing where they apparently think that rushing as many "epic" things into the plot as quickly as possible makes it better, whereas it in fact just cheapens them imo. BG3 is never at any point a "masterpiece of storytelling and plot development." What it does have is some pretty good *sidequest* writing, and really fun gameplay early on, and that fun gameplay helps to gloss over the weakness in the writing. It's later on, where the gameplay begins to unravel, that people begin noticing the lackluster plot more. This is compounded by the fact that the writing itself does genuinely decrease in quality as the game goes on.
Unfortunately in the case of BG3 I don't actually know if it will EVER be fixed. They've "fixed" things to a degree with definitive editions before. But BG3, of all their games, would probably require the most modifications to truly patch up and more importantly, making those modifications will be *more expensive and time consuming* than making modifications to any of their previous games.
Ultimately I think the tadpole powers were a curse, both from a narrative standpoint and a gameplay standpoint. They really, direly need to add some bad consequences for using tadpole powers. Narratively, though, they probably didn't want to give you a reason to distrust the guardian until THE BIG REVEAL. I think this is part of them WAYYYYYY overcorrecting to people not trusting Daisy during EA (who was an entirely much more interesting concept imo.)
Maybe the tadpole powers should have never been presented as tadpole powers. Like, maybe whoever is in your head, Guardian or Daisy, should have just presented them as "Divine gifts from a protector who is actually SHIELDING you from the tadpole." You could have even been manipulative with the icons: give the abilities pleasant-sounding names and nice-looking icons. But then maybe things start to feel a bit off the more "gifts" you accept. Maybe you use some of the abilities in conversation and people react with horror. Maybe later on you notice that some of the abilities you have seem weirdly similar to the abilities that the Absolute's servants have, they're just called different things. You would have to get rid of the whole "jam more tadpoles into your head for more powers" aspect, but that always seemed really silly to me to begin with.
