The idea was dropped, almost certainly for the better, and Avowed became the thoroughly singleplayer experience we've seen in its showcases. But in a recent chat with Windows Central, Obsidian shed a bit more light on the decision to go solo, particularly in the wake of the stonking success of Baldur's Gate 3 (and its co-op mode).
Source"It was a very big creative and technical challenge to find a way to build multiplayer while also fulfilling the things that we are strong at as a studio," said game director Carrie Patel. The things that Obsidian is good at, as you might have guessed, consists of stuff like "a really solid campaign and crit path story," that lets players make "impactful decisions, [while] really shaping the world and the characters around them."
