Over four million levels have been created on LittleBigPlanet, and Media Molecule reckon that if you spent 12 hours a day playing them, it would take you around 78 years to play through them all.
The crew also revealed that there would be a Tron: Evolution Minipack coming to the game soon, which will release on the 27th of April. It will contain two new costumes and a bunch of new stickers for £2.39.
In May, there will be a Killzone 3 Minipack, which will feature a Hazmat Sackboy Tropper, which of course, will be fully compatible with the Killzone costume kit that launched in the first game.
