Harrison cited God of War, LocoRoco, Shadow of the Colossus, Eye Toy and Singstar as examples of how Sony is trying to produce innovative software, saying they are, "things which wouldn't come out of perhaps a more conservative product development strategy, and certainly wouldn't come from a multi-platform third-party publisher".
He added: "It's something that as a platform holder we have a responsibility to grow the market, and to try and push the market. What I wanted to do here at GDC was paint a picture for where this industry should, I believe, move - which is to empower the user with user-created content. That's what I was referring to with the Game 3.0 aspect to my presentation."
