The short answer: Kingdom Hearts HD 1.5 + 2.5 ReMIX contains Kingdom Hearts Final Mix, Re:Chain of Memories, Kingdom Hearts II Final Mix, and 358/2 Days (as a movie); Kingdom Hearts HD 2.8 Final Chapter Prologue contains Dream Drop Distance HD, 0.2 Birth by Sleep – A Fragmentary Passage, and χ Back Cover (a movie); and Kingdom Hearts HD 1.5 + 2.5 ReMIX plus 2.8 together cover all mainline games up to Kingdom Hearts III. This article explains exactly what is in each collection, including the differences between the PS3, PS4, Xbox One, and PC versions.
Formula
The formula used in the calculator above is the standard pace formula: pace = time ÷ distance and speed = distance ÷ (time ÷ 60). In words, you take the total time in minutes and divide it by the distance in kilometers to get your average pace in minutes per kilometer. To get speed in kilometers per hour, you divide the distance by the time in hours (which is the total minutes divided by 60).
Variables:
- t – total time in minutes (e.g., 50 minutes)
- d – distance in kilometers (e.g., 10 km)
- pace – average time per kilometer, in min/km
- speed – average speed, in km/h
Worked Example
Using the default values from the calculator (50 minutes and 10 km):
- Pace = 50 ÷ 10 = 5.00 min/km
- Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h
So if you run 10 km in 50 minutes, your average pace is 5 minutes per kilometer and your average speed is 12 km/h. The calculator rounds to two decimal places, so you would see 5.00 min/km and 12.00 km/h.
What Are the Kingdom Hearts Collections?
Kingdom Hearts is a long-running action RPG series that spans multiple consoles, with a complicated timeline and several side games that are essential to the story. To help players catch up, Square Enix released HD remasters that bundle the games into collections. There are two main collections you need to know about: Kingdom Hearts HD 1.5 + 2.5 ReMIX and Kingdom Hearts HD 2.8 Final Chapter Prologue. A third collection, Kingdom Hearts HD 1.5 ReMIX and 2.5 ReMIX separately, exists only on PS3, but the combined version replaced it on PS4, Xbox One, and PC.
Kingdom Hearts HD 1.5 + 2.5 ReMIX – Full Game List
This is the main collection that covers the first two “chapters� of the series. It was released on PS4 in 2017, on Xbox One in 2020, and on PC (via Epic Games Store) in 2021. It contains:
- Kingdom Hearts Final Mix – the original PS2 game with extra content, fully playable in HD.
- Kingdom Hearts Re:Chain of Memories – the GBA game remade in 3D, fully playable.
- Kingdom Hearts II Final Mix – the second main PS2 game with added bosses and scenes, fully playable.
- Kingdom Hearts 358/2 Days – originally a DS game, but here it is presented as a 2.5-hour HD movie with all cutscenes, not playable.
- Kingdom Hearts Birth by Sleep Final Mix – originally a PSP game, fully playable in HD with extra content.
- Kingdom Hearts Re:coded – originally a DS game, also presented as an HD movie, not playable.
So the collection actually contains five playable games and two movies. The two movies are essential for story understanding, especially 358/2 Days which explains Roxas’s backstory.
Kingdom Hearts HD 2.8 Final Chapter Prologue – Full Game List
This collection was released on PS4 in 2017, on Xbox One in 2020, and on PC in 2021. It serves as a bridge to Kingdom Hearts III and contains:
- Kingdom Hearts Dream Drop Distance HD – originally a 3DS game, fully playable in HD. This game introduces the “Dream Eaters� and sets up the final saga.
- Kingdom Hearts 0.2 Birth by Sleep – A Fragmentary Passage – a brand-new short episode that follows Aqua in the Realm of Darkness. It is fully playable and acts as a prologue to Kingdom Hearts III.
- Kingdom Hearts χ Back Cover – a movie that shows the story of the Foretellers from the mobile game Kingdom Hearts χ. It is not playable.
So 2.8 contains two playable games and one movie. The playable episode 0.2 is short (about 3-4 hours) but important for the story.
What About Kingdom Hearts III and Melody of Memory?
Kingdom Hearts III is not part of any collection. It is a separate full game, released in 2019 on PS4 and Xbox One, and later on PC. It includes its own DLC, Re Mind, which adds a new scenario. After III, there is also Kingdom Hearts Melody of Memory, a rhythm game that recaps the story but is not in any collection. If you want the complete story up to III, you need to buy both collections plus Kingdom Hearts III separately.
How to Choose Which Collection to Buy
If you are new to the series, the best starting point is Kingdom Hearts HD 1.5 + 2.5 ReMIX because it contains the first two main games and the most important side games. After finishing that, you should play 2.8 because it leads directly into Kingdom Hearts III. If you already own the PS3 versions, upgrading to the PS4 combined collection is worth it because it includes all six games on one disc (or digital download) with improved load times and 60 FPS on PS4 Pro and Xbox One X.
For PC players, both collections are available on the Epic Games Store, but note that they are sold separately, not as a bundle. On Xbox, the two collections are also separate purchases. On PS4, there is a physical disc that contains both collections, but the digital versions are separate.
Common Problems and Misconceptions
One common misconception is that 358/2 Days and Re:coded are playable in the 1.5+2.5 collection. They are not – they are HD movies. If you want to play the original DS games, you would need a DS or 3DS and the original cartridges, which are not included in any collection.
Another issue is that the PS3 versions of 1.5 and 2.5 are separate discs and do not include all the Final Mix content that the PS4 version does. The PS4 version is the definitive one because it includes all Final Mix content from both games. Also, the PC versions require an Epic Games Store account; they are not on Steam.
Some players are confused about the order of play. The recommended order is: 1.5 (which includes KH1, Re:Chain, 358/2 Days movie), then 2.5 (which includes KH2, Birth by Sleep, Re:coded movie), then 2.8 (Dream Drop Distance, 0.2, Back Cover). This order follows the story’s release and chronological flow, though the timeline is not strictly linear.
Cost and Availability
Prices vary by platform and region, but generally each collection costs around $30-40 USD at launch, and often goes on sale for $15-20. The physical PS4 disc that includes both collections is sometimes sold as “The Story So Far� – that is the same content as 1.5+2.5 and 2.8 combined. On Xbox and PC, you must buy the two collections separately. On PS5, the PS4 versions are playable via backward compatibility, but there is no native PS5 version.
Alternatives: The All-in-One Package
If you want everything in one purchase, look for Kingdom Hearts: The Story So Far – that is a PS4 bundle that includes both 1.5+2.5 and 2.8. It does not include Kingdom Hearts III. For a complete set, you would need to buy The Story So Far plus Kingdom Hearts III (and its Re Mind DLC if you want the extra story). On PC, there is no all-in-one package; you buy each collection and III separately.
Frequently Asked Questions
Q: Is 358/2 Days playable in the 1.5+2.5 collection?
A: No, it is only a movie. The original DS game is not included as a playable game in any collection. You would need a DS and the original cartridge to play it.
Q: Do I need to play 2.8 before Kingdom Hearts III?
A: Yes, 2.8 contains Dream Drop Distance and 0.2, which directly set up the events of III. Skipping them would leave you confused about the characters and plot.
Q: Are the collections available on Nintendo Switch?
A: No, there is no native Switch version. The only Kingdom Hearts game on Switch is the cloud version of Kingdom Hearts III, which requires a stable internet connection and is not recommended for most players.
Q: What is the difference between the PS3 and PS4 versions of 1.5 and 2.5?
A: The PS4 version combines both into one disc and includes all Final Mix content. The PS3 versions are separate discs and lack some of the quality-of-life improvements and the 60 FPS mode.
Q: Can I play the collections on PS5?
A: Yes, the PS4 versions work on PS5 via backward compatibility. They run at the same resolution and frame rate as on PS4 Pro, which is typically 1080p or 1440p at 60 FPS.
Q: Is Kingdom Hearts III included in any collection?
A: No, Kingdom Hearts III is a separate game. It is not part of 1.5+2.5 or 2.8. You must buy it separately, and the Re Mind DLC is also separate.
