LittleBigPlanet, commonly abbreviated LBP, is a puzzle-platformer video game, based on user-generated content, for the PlayStation 3 first announced on 7 March 2007, by Phil Harrison at the 2007 Game Developers Conference (GDC) in San Francisco, California. It was developed under the title The Next Big Thing by Media Molecule and was published by Sony Computer Entertainment Europe. Many saw the game as an important title for Sony's PlayStation 3.
The game received an overwhelmingly positive reaction from critics and has been praised for its presentation, including its graphics, physics, and audio, along with its gameplay and large array of customisable costumes and online features. Additional praise was given to its scope and future potential based on user-created content; minor criticism was reserved for specific elements of the gameplay mechanics and level creation facilities. LittleBigPlanet has won a considerable number of awards. A PSP version of the game was released in November 2009, featuring new levels and content. The game was offered by Sony as a free download as part of their 'Welcome Back' program, following the PlayStation Network outage of 2011.
