Sony really needed a virtual pet though, especially for the Japanese market. Think Pikmin, Harvest Moon and Tamagotchi/Furbies, and Black and White. And Nintendogs. The gameplay and interaction elements could go down a storm to the whole virtual pet and creature raising fans. I'm sure Nintendo would have a killer experience using augmented reality with Pokemon!The card game itself is pretty standalone and according to people, fun. So you're correct to say that PS Eye is not needed. But the "augmented reality" concept is fascinating and has never been done in mass market before.
