In the glued and stitched-together 3D landscape of LittleBigPlanet for PS3, players have the power to design, shape and build both objects and entire locations for others to view and play. There's no complicated level editor in LittleBigPlanet; all of these skills can be learned by simply playing the game. Creativity is part of the LittleBigPlanet PS3 gameplay experience and playing is part of the creative experience. LittleBigPlanet 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.
Could probably have had it cheaper a year back but cheapest around at the moment me thinks. :)
