Ever since Final Fantasy made its way into the Playstation era, translations have improved a great deal in international releases and FFX-2 was no exception. I really liked the way Square-Enix modified certain dialogues to suit each character's English tone, such as Gippal and Yuna's dialogue upon their first encounter at Djose Temple.
Nevertheless, a three-way interpretation is more fun than two, and that's what I'll offer at my site: not only will you find Lenne's complete script taken from both versions of FFX-2, I also attached a word-to-word translation of my own, marked in light blue. Have fun comparing it with the official English script!
