The game revolves around the player's control of a small character, known as a Sackboy or Sackgirl or gender-neutral Sackperson owing to their appearance, in a variety of platforming scenarios. Though the game features a set of pre-built levels for the player to explore, the game's customisable nature is equally important, from altering the player's character and personal space, to building entirely new objects and levels, and then sharing and playing them online with other players as part of the LittleBigPlanet community.
