Dissidia Final Fantasy was originally envisioned by creative producer Tetsuya Nomura as a Kingdom Hearts spin-off featuring a cast of Disney characters while the Square Enix staff were developing Kingdom Hearts II.[17] Nomura later felt uncomfortable with the Disney characters fighting each other and instead opted to use Final Fantasy characters, although the original idea eventually gave rise to the development of Kingdom Hearts 358/2 Days, with the game's multiplayer mode inspired by Dissidia's gameplay.[18] The game was made in commemoration of the franchise's 20th anniversary and despite being handled by young employees, Nomura noticed there was no pressure, having assisted them in the designing various areas from the gameplay.[3] The game was directed by Takeshi Arakawa whom Nomura noted that his experience in a previous Square Enix game, The World Ends With You, had a good effect in the game.[19] To have their desired way of fighting, the team chose the PlayStation Portable console.
