Baldur's Gate 3 is arguably one of the biggest and best games to launch this millennium, with D&D holders Wizards of the Coast and RPG specialists Larian Studios coming together to make something truly special. Looking back on it now, it felt like a match made in heaven, but Larian CEO Swen Vincke recently revealed that there were two other big franchises that the studio wanted to work with if Wizards of the Coast didn't want to play ball.
In an interview with Edge Magazine (thanks GamesRadar), Vincke says that there "was not a lot to choose from" when it came to big RPGs that could match the ambitions that Larian had at the time, and that the only realistic options were Baldur's Gate, Fallout, and Ultima. Those choices make a lot of sense, especially when you consider the top-down CRPG roots of the first two Fallout games that were made by Interplay and Black Isle Studios.
Black Isle Studios also happens to be the publisher of Baldur's Gate too, though it was developed by BioWare.
Of course, you could probably spend all day thinking up RPGs that Larian could work on, and there would be plenty of hype...
