- Translations, Upscaled visuals/audio, controller reworkings, and censorship don't count as differences.
- Kingdom Hearts Vcast and Mobile aren't counted, as Vcast wasn't developed by Square Enix/Squaresoft and neither games are considered canon.
- Kingdom Hearts 358/2 Days HD, Kingdom Hearts χ Back Cover, and Re:coded HD aren't counted, as they only serve as a cinematic feature and unlocking criteria for the other games, rather than games themselves.
- With all of this in mind, the statement "Kingdom Hearts 3 is the 25th version of a Kingdom Hearts game to be released" is entirely accurate. Also, "Kingdom Hearts 3 is the 20th game to be released" is also accurate.
