Bethesda Rejected Multiple Elder Scrolls Spin-Off Pitches from Obsidian

Proposed games were intended to serve as 'New Vegas' style spin-offs, providing additional adventures in the Elder Scrolls universe.

Obsidian Entertainment, known for its work on Fallout: New Vegas, pitched multiple Elder Scrolls spin-off games to Bethesda, all of which were rejected.
Chris Avellone, ex-Obsidian writer, confirmed that one of the proposed Elder Scrolls games was intended to serve the same function as Fallout: New Vegas, providing more adventures in the setting during the years before the next Bethesda release.
Avellone suggested a system similar to what Treyarch/Activision had with Call of Duty, where Bethesda would release a core game and Obsidian would release a spin-off title in the same world or a divergent timeline.
One proposed concept was an alternate timeline or parallel universe of Tamriel, where heroes from previous titles had failed to 'save the world.'
Despite the rejections, the possibility of Obsidian creating an Elder Scrolls game or another Fallout isn't too far-fetched, as both Bethesda and Obsidian are now Xbox first-party studios.
