Bungie was apparently trying to get cross-platform character transfer for Destiny 2 players, but were prevented from doing so by Sony, at least according to Kotaku reporter Jason Schreier.
In a recent episode of the Splitscreen podcast (at around the 57-minute mark), Schreier claims to know about a plan within Bungie to get the ability to transfer characters in Destiny 2 across different platforms. So, for example, transferring your Guardian from a PS4 version of Destiny 2 to the PC version of Destiny 2.
Unfortunately, Bungie has an exclusivity deal with Sony, and the company prevented the developer from going through with the cross-platform transfer plans. "I heard that Bungie wanted to do character tranfers for PS4, PC–before Forsaken came out–but Sony wouldn't allow it," Schreier said. "Sony is just like, 'we want people to associate Destiny with PS4,' even if that means screwing over other players. It sucks and hopefully Bungie ends it."
The feature would have been particularly useful when at BlizzCon last year Bungie announced that players on Battle.net could get a copy of the base version of Destiny 2 for free. These discussions also seemingly pre-dated Bungie's divorce with publishing partner Activision.
Sony is also known to block certain cross-platform initiatives. Developers like Epic Games and Psyonix have long called for cross-platform gaming, and successfully integrated the feature between Xbox, Nintendo Switch, and PC hardware. But Sony refused to allow cross-platform play until it did so with Fortnite. Though, some devs still believe they're locked out of enabling cross-platform play on PS4.
Sony's exclusivity with Destiny 2 and Bungie remain, despite Bungie's split from Activision. However, Bungie could revisit this strategy if or when it decides to publish either a new IP or sequel to Destiny 2. Check out our Destiny 2 guide for more of our coverage on Bungie's popular loot shooter.
