Days Gone, developed by Bend Studio, emerged as a unique entry in the PlayStation 4's library, offering an open-world experience infused with zombie apocalypse themes. More importantly, it was hyped ahead of its launch, with audiences eagerly awaiting the experience that it could offer following its initial reveal at E3 2016. Unfortunately, it didn't quite get as much acclaim when it came out in 2019. This hurt more considering that it was supposed to be one of the big first-party Sony exclusives the year that it was released, following the success of titles like God of War, Horizon Zero Dawn, and Marvel's Spider-Man, all three of which have spawned franchises since.

Part of the reason why Days Gone didn't get a sequel was apparently due to its lack of sales at launch and mixed critical reception. However, it appears that Days Gone, despite a slow start, eventually recovered, selling over 7.2 million copies on console and 800,000 on PC.

This puts Days Gone with sales numbers at around the 7 million to 8 million mark, which means that it outsold Ratchet & Clank and Death Stranding, both of which got sequels while it didn't. This, plus the fact that it ended on a cliffhanger ending, makes fans wonder, why is Sony not working on Days Gone 2?

The bromance between Boozer and Deacon was one of the highlights of Days Gone.
