Final Fantasy X started off with a sad world, but Spira was in a better place after Tidus and Yuna’s journey. Then Final Fantasy X-2 came along and the pop motif made everything feel happy. However, a melancholy tide came in with the Final Fantasy X/X-2 HD Remaster radio drama and the novel Final Fantasy X-2.5 from story writer Kazushige Nojima.
When Siliconera spoke with Final Fantasy X producer Yoshinori Kitase we asked him why Spira is such a sad place again. "We met with the original script writer, Kazushige Nojima, for Final Fantasy X/X-2 HD Remaster and we were brainstorming about the world after X-2. We wanted to have the story continue as a direct opposite of Tidus and Yuna’s happy story in Final Fantasy X," Kitase replied. "Sin is a character we created as a symbol of natural disasters like a typhoon. He brings disaster and sadness to the world. And, Spira resides right next to death."
But, why bring back Sin at all? I talked to Kitase about how the entire journey of Final Fantasy X was breaking the cycle of Sin and bringing Sin back as a character kind of erases all of the work Tidus, Yuna, and the player achieved.
"Similar to how Sephiroth’s role in Final Fantasy VII, Sin plays a very important role in Final Fantasy X and we wanted to keep Sin involved [with the story]," said Kitase. "We can’t say what happens to Sin after the radio drama, we wanted to leave something up to the player’s imagination," said Kitase.
