LittleBigPlanet was first announced by Harrison at Game Developers Conference 2006. Harrison lauded the concept and agreed to fund the project. After a prototype called Craftworld was created in 2006, it was pitched to Sony Computer Entertainment Worldwide Studios president Phil Harrison. The concept of a game that allowed the player to be creatively ambitious for the console was envisioned after a movie trip to Howl's Moving Castle. Media Molecule was formed by four former Lionhead Studios employees after the release of Rag Doll Kung Fu (2005). The story mode revolves around Sackboy helping various Creator Curators around LittleBigPlanet before facing the Collector, who has been kidnapping and stealing creations. They are grouped into areas, each centring around a theme. The premade levels in the story mode are built around Sackboy's basic control scheme. The level editor is the main focus of the game, allowing the player to create levels and publish them online.

The first game of the LittleBigPlanet franchise, the player character is Sackboy, a brown ragged doll with the ability to create. LittleBigPlanet is a 2008 platform game developed by Media Molecule and published by Sony Computer Entertainment for the PlayStation 3.
