Larian CEO is "frightened" by Baldur's Gate 3's success but it's "very motivating" for "our next big game"

I guess that's fair, though I think Larian coming from D:OS and D:OS2 (and earlier Divinity games) have a bit more experience with defining scope for a larger game than CDPR, which basically just had Witcher 1&2.
So I'm not too worried about Larian biting off more than it can chew.
