If you're looking for something in the same genre as BG3: 'Planescape: Torment' ( https://en.wikipedia.org/wiki/Planescape:_Torment ) is the game which revolutionized that genre once and it's legally available for a relatively low price.
Similar things can be said for 'Disco Elysium' ( https://en.wikipedia.org/wiki/Disco_Elysium ), but that thing runs on the 'Unity Engine' which means it could refuse to run either temporarily or permanently without much of a warning.
Other than that, you can check out the "Other Favorites" category* on the profiles of users you share the same taste with. The links are hardwired to redirect you to the slave-labor company that is Amazon, though - so don't click them.
And if none of that works out for you, I'd recommend the search on https://itch.io/ . ('Bastion', 'CrossCode', 'Minit', or 'OneShot' might be for you...)
Best of luck!
