When Kingdom Hearts 4 eventually launches, the Kingdom Hearts All-In-One Package will no longer live up to its name. Released in 2020, this comprehensive collection was intended to serve as a definitive way for fans to experience the Kingdom Hearts series. The collection includes Kingdom Hearts HD 1.5 + 2.5 Remix, Kingdom Hearts HD 2.8 Final Chapter Prologue, and Kingdom Hearts 3, offering an expansive look at the series’ mainline storylines. The collection already had some notable exclusions upon release, and with the arrival of Kingdom Hearts 4, it will feel even more incomplete.
