Studiet bag Divinity Original Sin-serien, Larian, har ikke lagt skjul på at Baldur's Gate III er det største projekt de nogensinde har haft med at gøre. Faktisk er det så omfattende, at de blev nødt til at tredoble studiets samlede antal ansatte, for alt andet ville betyde at de blev nødt til at gå på kompromis med ambitionsniveauet.
Under et interview med IGN ved GDC fortæller Creative Director Swen Vincke, at de forventede at projekt ville kræve meget, meget mere end Divinity 1 og 2, men at de stadig undervurderede mængden af arbejde associeret med udviklingen. IGN fortæller følgende:
"As Vincke explains in his talk, Larian prepared itself for its biggest game ever. The studio spent over a year in pre-production, hired for many new positions, and made the best projections it could for how many words the game would have, how much recording time would be needed, what would have to happen to make all the cinematics, and so much more. But ultimately it wouldn't be enough on its own, in no small part because of the enormity of trying to convert the complexities of a Dungeons & Dragons game — where players can do anything they can think of, effectively — into a video game system."
Larian har allerede slået fast, at spillet ikke går ud af Early Access i år, men at de i stedet sigter en endelig lancering på PC i 2023.
