Especially since most of the games included on the list are major game releases from AAA game franchises. Optimizations aren't a certainty, but it's unclear what else the mysterious Xbox 360 game patches could be for. However, there's an opportunity to release optimization patches for each of them to improve their performance or enhance them in more straightforward ways, whether solely for the Xbox Series X and Xbox Series S or for the Xbox One as well. Obviously, new content for these aging games is almost certainly out of the question. While there's nothing certain surrounding the situation, speculation points to the 20th Anniversary as the reveal and official release of these updates and their nature. RELATED: Xbox Announces 20th Anniversary Broadcast The existence of these updates is all that anyone knows, as there's no indication that the updates have activated in-game as of yet. The nature of these updates has yet to be discovered. The games include Major Xbox 360 releases like Fable Anniversary, Fallout New Vegas, Assassin's Creed, The Elder Scrolls 4: Oblivion, Dead Space, Dragon Age: Origins, and many more. Multiple online sources are reporting that a significant update rolled out to over fifteen different Xbox 360 games this weekend. The latest evidence of this revolves around more than a dozen Xbox 360 games seemingly receiving updates overnight, the content of which remains mysterious.
