Larian Studios makes good games, but by no means are they a "gold" standard.
The Divinity series has a very interesting take on the RPG genre that's not to everyone's liking. And their world-building chops so far are somewhat lacking, compared to the original Baldur's Gate series.
It's also going to be interesting how faithful it is to the mechanics of D&D, and whether Larian again will make a game where you have to scrape by every right, rather than feeling like a powerful RPG character.
