The Last Guardian was originally meant to be a PlayStation 3 exclusive but – after several delays – it was released for PlayStation 4 only. Today Sony's Worldwide Studios Head, Shuhei Yoshida, admitted that they failed to release the game on PlayStation 3 due to technical difficulties and hardware limitations.
"Simply, we failed!" he said. "We decided, no, we cannot make it. The trailer that we showed at E3 2009 was speeded up. It was from the development system but we took it frame by frame and made it run smoothly."
"Because of the technical difficulty, running the game at the frame-rate required that the team look to compromise some features - the number of characters that Ueda-san wanted to do - if we were to continue on PS3," added Yoshida. "But because we moved to PS4, now he can make what he wanted. So people say it looks like the same game - there's a reason!"
