I really loved Ico and Shadow of the Colossus. Haven't tried the Last Guardian yet. I am kind of surprised he is still working on games though. I thought he stopped working for Sony about 10 years ago, and I haven't heard from him since.
As I understand it, he left Sony in the middle of TLG development and formed a new studio called genDesign which was responsible for the creative process of TLG while Sony Japan worked on implementation
