LittleBigPlanet, sometimes abbreviated to LBP and developed under the title The Next Big Thing, is a puzzle platformer and user generated content video game for the PlayStation 3, first announced on 7 March 2007, by Phil Harrison at the 2007 Game Developers Conference in San Francisco, California. It is developed by Media Molecule, a British company founded in part by Rag Doll Kung Fu creator Mark Healey and published by Sony Computer Entertainment Europe.The game revolves around the player's control of small avatars, known as Sackboys owing to their appearance, in a variety of platforming scenarios. Though the game features a set of pre-built levels for players to explore, of equal importance is the game's customisable nature, from altering the player's character and personal space, to building entirely new objects and levels, and then sharing and playing them online as part of the LittleBigPlanet community.
