Anybody who thought that the PSN-friendly nature of LittleBigPlanet meant the game could be offered as a downloadable title will probably dash that dream when they find out the game takes up 40GB. In an interview with GI.biz, developer Alex Evans explains the game will be \"filling up\" the Blu-ray disc.

Evans explains there's a lot of tutorial content in LittleBigPlanet, narrated by Stephen Fry for English audiences. As we've learned in the past from Heavenly Sword and Ratchet, it's the (uncompressed and/or multi-region) audio that takes up a significant amount of space on the Blu-ray. Evans expresses that thanks to the Blu-ray, file size hasn't been a concern. This loose attitude to size for the disc's contents will not be applied to the player-designed content, however, which Evans says is \"relatively compact.\"
