Hmm... I totally get the appeal of "just playing the game" without having to micromanage your gaming experience, although I myself much prefer being able to micromanage my difficulty settings (probably because I come from a turn-based tactical game background), but the thing is, it really would not make sense to have little to no options in BG3 nor do I think it is a reasonable thing to ask for. Allow me to explain my reasoning:

1) Baldur's Gate is a series based on Dungeons and Dragons (D&D / DnD), set in one of most popular universes of said game.
And why does that matter? D&D is a game that is literally *built* on the idea of customizing a tailor-made campaign for a unique party of players. D&D can as easily be played by number crunchers who just want to dungeon crawl, do tactical encounters and get loot, as it can be played by heavy RPers that want to spend multiple sessions to just RP around in a city or village. Most parties want some kind of balance between combat and RPing - but it is completely individual how much one prefers one activity before another. Some people want 50-50, some 40-60, 20-80 and some want no dice/stat combat, alternatively no RPing, at all.

The only reason D&D manages to carter to such an enormous and diverse audience is because of the customization. Said customization usually involves a session zero; a meeting or gathering where all players and the DM discuss and (hopefully) agrees on a set of rules to make their table comfortable and fun for everyone involved. The way I see it, the option list is pretty much the "session zero" of a cRPG. I decide together with my DM (Larian, in this case) how I want to play the game and Larian tries their best to tailor the campaign based on my preferences (while still holding on to their base idea - aka, the core of the game). To me, having options regarding the difficulty (i.e "Oh, I'd like to focus on RPing so please make encounters a bit easier") is as valid as wanting to cut out specific things that may or may not be uncomfortable/non-interesting - like the nudity scenes ("I am not really comfortable with ERPing, could we skip those parts and focus on the emotional bits?") or even turn off romance entirely.

2) Larian's game history includes a lot of customization, "homebrew" and options.
DoS2 have different difficulty settings and a lot of options on top of that (referring to the menu with loads of boxes that can be checked/unchecked). To many players' despair (and some other players' great joy), Larian has chosen to include a lot of stuff from DoS2 to BG3 and cutting general options and game customization out of the equation would be a... Very interesting move (and not in a good way imo). Point being - Larian has a history of wanting to give players options and hence, I believe it would be unreasonable to expect them to shy away from this philosophy now. *Especially* when they are picking up the torch of a very well-respected game legacy within the CRPG genre.

Hoot hoot, stranger! Fairly new to CRPGs, but I tried my best to provide some feedback regardless! <3 Read it here: My Open Letter to Larian
