IGN: LittleBigPlanet Preview

Part of LittleBigPlanet's genius lies in how flexible the tools themselves are. Any object can be scaled from tiny to utterly mammoth, cut into pieces, remove chunks cookie-cutter style with shapes, link them together and jam them all over the place.
Sounds like it offers simplicity and complexity (in what you can create) to designing levels for it.

October release here apparently.
