LittleBigPlanet

Media Molecule, the makers of the wildly addictive Rag Doll Kung Fu, now brings its talents to PlayStation 3. Given the cheeky working title The Next Big Thing™, LittleBigPlanet is a game that is also a game-making studio.
The LittleBigPlanet experience starts with players learning about their character's powers to interact physically with the environment. There are obstacles to explore, bits and pieces to collect and puzzles to solve – requiring a combination of brains and collaborative teamwork. As players begin to explore, their creative skills will grow and they will be ready to start creating and modifying their surroundings – the first step to sharing them with the whole community. Creativity is part of the gameplay experience and playing is part of the creative experience. Players can make their world as open or as secretive to explore as they like. When it's ready, they can invite anyone within the LittleBigPlanet community to come and explore their patch -- or can go and explore everybody else's.
