The first Kingdom Hearts games have finally hit a non-Sony platform.
Kingdom Hearts Xbox One

Square Enix and Disney just released the first few Kingdom Hearts games on the Xbox One today. This marks the first time ever that the first main Kingdom Hearts titles have been released on a non-Sony platform. While today's release may not include Kingdom Hearts III, it does features a combined nine adventures to experience.

At $49.99 (USD), you can first pick up Kingdom Hearts - HD 1.5+2.5 ReMIX -. This release includes 6 of those 9 Kingdom Hearts experiences and is precisely where those who have never played the franchise before will want to begin their adventures. In short, this release includes the first two games and a bunch of bonus content that is either included as part of the games or as cinematics that includes more plot points.

After that is the $59.99 (USD) release of Kingdom Hearts HD 2.8 Final Chapter Prologue. This release includes an HD remaster of Kingdom Hearts 3D: Dream Drop Distance, Kingdom Hearts 0.2: Birth by Sleep, and Kingdom Hearts x Back Cover. The story is all over the place, including partly taking part during the events of the first Kingdom Hearts game. Just play the games in numbered order, which I guess for all of these would be HD 1.5+2.5 ReMIX and then HD 2.8. If you don't understand the plot after all that, I wouldn't worry about it too much, nobody else does either.

In total, these two compilations should give you "over 100 hours of Kingdom Hearts adventures."

Speaking of Kingdom Hearts III, Square Enix says that the Re Mind DLC for the game will be be released on the Xbox One starting on February 25. This DLC will retail for $29.99 (USD) at launch. This is the same expansion that came out on the PlayStation 4 on January 23, 2020. There will also be a package that contains the Re Mind DLC plus footage from the Kingdom Hearts - World of Tres - Orchestra concert from a performance in Osaka, Japan. This package will go for $39.99.

On top of this, Kingdom Hearts III will be added to Xbox Game Pass starting February 25. Though subscribers to Game Pass will get access to the full base game, the Re Mind DLC will still need to be purchased separately.

Fans will join Sora, Donald, Goofy and other familiar Disney characters as they journey through Disney worlds to stop the Heartless invasion and save the KINGDOM HEARTS universe from darkness. Keyblade wielders will befriend and enlist beloved Disney and FINAL FANTASY characters to help light overcome the darkness.
