TL;DR: We need more choice not less. This posts outlines implementing a way to make an even more customizable experience to try and satisfy as may play styles as possible without imposing a "meta game" or "Right way to play".

There are a handful of games out there have custom difficulties (RimWorld; the last of us 2; Transistor, etc...) and after browsing all these suggestion in the feedback section I think Baldur's Gate 3 would really benefit from it too.

There are so many people with so many different play styles in here from casual to hardcore and it's impossible to make a one size fits all to satisfy everyone. That is super clear when reading this section and you can see a lot of people here basically telling other people that they are enjoying the game incorrectly or indirectly stating that others aren't playing the game properly because they like to use certain mechanics a certain way or they try shoot down QoL suggest because they think a hide helmet option breaks immersion or say things like "why do you need a bag of holding? you should only be carrying xyz" or whatever.

Variant Rules and Homebrew have been cornerstones of the D&D experience for a very long time; basically from the beginning. We all know modders will take care of the Homebrew stuff; but Larian has an opportunity to take a lot of these pieces of feedback and incorporate a way to customize the experience for us players.

For example; don't like how HP bloat? Don't want to see the DC or tool tip on your dialog choices? Think that "magic pocket" breaks immersion? turn them off. Now i know what you're thinking "I don't want to look at a spreadsheet of features to toggle before I play the game, I just want to make my character and get started..." Good, me too.

my solution to that is.... well... more choice; but keeping it to simple to presets. basically the standard choices that Larian is already planing but then just add a "Pen and paper mode" where the options that most closely resemble the pure 5e are selected blind DCs and all. The other one being Custom where you can do what outlined above.
