KINGDOM HEARTS - FINAL MIX
Kingdom Hearts: Final Mix is the special edition version/extended version of the original game. This version includes various bonus and extended content. This edition was originally only released in Japan. However, due to the release of the HD remastered collection of Kingdom Hearts games known as Kingdom Hearts HD 1.5 Remix this version has since become available in North America and Europe.
The cover art for the game case itself is entirely different from the original one.
