LittleBigPlanet Generator (lost "LittleBigPlanet" promotional Flash game; 2008)
From The Lost Media Wiki
LittleBigPlanet Generator is a Flash game released in late 2008 to promote the PlayStation 3 title LittleBigPlanet. You could customize a 3D Sackboy and share it online. The game was hosted on http://mysackboy.littlebigplanet.com/, but seems to have been taken down sometime in 2011. None of its files have been resurfaced. Videos and screenshots of it still exist, however.
