to convey his concept. Following the target platform switch, Ueda and other members of Team Ico were not as involved with the process, as other teams worked to take the highly customized PlayStation 3 code to adapt it to the PlayStation 4; this included the help of PlayStation 4 lead architect Mark Cerny. With the reintroduction of the game at the E3 2015, Yoshida explained that the game engine is now fully running at speed on the PlayStation 4 and that the remainder of the development lies with the game designers to complete. Development was hampered by Ueda's departure from Sony in December 2011. With Sony's decision to delay the release of the game early that year, Ueda and other Sony and Team Ico employees opted to leave Sony. Ueda stated in 2013 interview that his departure from Sony was due to feeling "a sense of crisis within myself about a lot of things" on news of the delay. Some of those that departed Sony went on to other projects. For example, executive producer Yoshifusa Hayama joined Bossa Studios to work on social/mobile games, while two Team Ico artists joined an indie startup studio Friends & Foes to develop their first game, Vane, which has been compared visually to The Last Guardian. Ueda and other former Team Ico members, including Jinji Horagai, the lead programmer from Ico and Shadow of the Colossus, created a new studio, GenDesign. In founding the studio, they were faced with a choice, according to Ueda: "Do we try to create something new, or do we keep going, providing support on The Last Guardian?" GenDesign opted to commit themselves to helping Sony complete The Last Guardian through contract and working alongside Sony's internal studio, Japan Studio. Under this arrangement, GenDesign developed the creative content for the game, such as character design and animation and level design, which was then put into place via Japan Studio, with Ueda maintaining oversight on the completed project. Ueda stated that the final game, as of June 2016, still represents the initial vision he had for The Last Guardian at its onset. The transition from the PlayStation 3 to 4 only improved how the game looked, but did not change how it played. Ueda stressed it was important during the extended development cycle to keep the question "what kind of game do I want to play?" at the forefront, and to
