The Games on Demand version of Tales of Vesperia was last confirmed available in North America on February 9, 2022. By March 30th, the game’s availability was questioned on the game’s TrueAchievements.com page.
The cause for the delisting is uncertain. Possibilities include changes to Namco’s corporate structure over the years and across the regions. Some older releases are credited simply to ‘Namco’ where newer titles read ‘Namco Bandai Games’, neither of which represent the current entity of ‘Bandai NAMCO’. The game may also have been delisted to entice players towards the newer Tales of Vesperia Definitive Edition release.
