Baldur's Gate 3 II: The Urge for a Second Playthrough

[Errorname]

That's basically just Solasta. Which is a fine combat simulator with a sort of story linking the stabby bits. Honestly they tried as hard as I think you realistically can to make interesting conversations with all custom characters, since everybody gets their own sets of tags and likes/dislikes, but it's pretty flat in practice.

Yeah, I think if you actually wanted to do an Icewind Dale 3 giving you the option to you customize the party if you want to, but also having robust and well developed premade characters is the obvious best option, especially considering current expectations. That's basically what Pillars of Eternity did and considering where Sawyer and co cut their teeth that's basically an Icewind Dale successor already, especially the expansion.
