 The developers had difficulty with Tidus and Yuna's kissing scene, since they were unaccustomed to animating romantic scenes.According to Visual Works director Kazuyuki Ikumori, this was due to the use of 3D models, and it was revised several times due to a negative response from female staff members.Director Yoshinori Kitase said that in the development of "Final Fantasy X", one of the staff's main objectives was to focus on the romance between Tidus and Yuna.
