Fumito Ueda, the director and designer of acclaimed PS2 titles Ico and Shadow of the Colossus, has apologised to fans for the lengthy delay in releasing The Last Guardian, the next game from Sony's Team Ico.
In an Edge interview reflecting on his career to date, Ueda was asked how taxing the past eight years have been on him as a creator.
"Putting aside the short-term output, more than anything I feel terribly sorry that for various reasons I have kept my audience waiting for such a long time," he replied.
While Ueda confirmed that he is still working on The Last Guardian, he said most of his creative contribution to the title was completed some time ago, and suggested that Team Ico's pursuit of perfection has slowed development of the game.
"The original staff members on Ico and SOTC are just as fussy over details as I am," he explained. "I always want to create quickly, and I always want to increase the rate of production.
"In the case of The Last Guardian, my creative work was mostly finished a long time ago, but the details of when, where and how it will be completed are beyond my control."
Ueda resigned from Team Ico in November 2011 but has continued to work on The Last Guardian in a freelance capacity. Explaining his decision to leave the studio, Ueda said it was down to a personal "sense of crisis... in terms of my own growth and career".
Asked about Sony's response to his desire to leave, Ueda said: "It was not easy, but I can't go into the details just yet. It will be good to be able to discuss it along with a post-mortem of The Last Guardian someday."
The Last Guardian has not been shown publicly since 2010. Sony Worldwide Studios president Shuhei Yoshida said in October that the game was being re-engineered, fuelling rumours that the long-delayed title will now ship on PS4 instead of PS3.
