Once it actually comes out, Final Fantasy X and Final Fantasy X-2HD will offer the most complete version of X-2 ever released in the US. Following earlier reports of extra content, Square Enix Producer Yoshinori Kitase told Siliconera that the remastered bundle will include X-2's content from its PS2 re-release, Final Fantasy X-2 International + Last Mission.
"In addition to the Last Mission from X-2, additional dresspheres and the Creature Creator will be included in the game," Kitase said.
Similar to Final Fantasy XIII-2's Paradigm Pack that lets players enlist monsters as teammates, Creature Create allows players to capture monsters and swap them into their party in place of Yuna, Rikku or Paine. This was also possible for human characters, including FFX cast members Lulu and Kimahri or NPCs like Seymour Guado.
