Sony dearly hopes LittleBigPlanet will kickstart a much-needed spike in PS3 sales. Luckily it proves to be a work of genius. It's a game in two parts, with a conventional (but achingly cute) platformer which combines cunning physics with a gloriously simple control system. But the most amazing element is a full-blown, unbelievably powerful yet easy to use editor, which lets you make your own levels to post on the PlayStation Network. It should, therefore, unleash a torrent of creativity – when the release finally happens next month.
