(adsbygoogle = window.adsbygoogle || []).push({}); LittlerBigPlanet, as I'm referring to it as, popped up on Amazon.com today. The PSP version of the PS3's very successful platformer is currently listed at an MSRP of $49.99 (Amazon is selling it for $42.99). The listing also confirms that the game will be released on October 31st. Additionally, I'm sure the game will also be available via download through the online PSP Go store.
