Upcoming world creation game LittleBigPlanet has gone gold, and will be officially released on Oct. 21st in the US. The game will come out exclusively for the PS3, in part due to the fact that it fills up a Blu-ray disc. The list of trophies was leaked alongside the announcement. Groups of students at Parsons will be using a 24-hour period this weekend to create levels for the game. Gamespy has a collection of videos and previews for LittleBigPlanet. To protect users' creations, it will feature an in-game copyright system.
