Also at GDC 2007, Sony and Media Molecule introduced LittleBigPlanet, a genre-defying, physics-intensive, community-based game with a hugely innovative concept behind it. Players meet on a blue and green planet scattered with individual plots - and use their character's amazing abilities to play, create and share what they build with other gamers throughout the world via PlayStation Network. The man behind LittleBigPlanet is Mark Healey, formerly of Lionhead and creator of Rag Doll Kung Fu.
