Steven Isbell, Community Coordinator for LittleBigPlanet, has revealed that costumes purchased in LittleBigPlanet 2 will be cross-compatible with titles including LittleBigPlanet on the PS Vita and LittleBigPlanet Karting. This means that gamers will be able to use their purchased costumes across any game at no extra cost.
The costumes are not directly compatible so the developers are working to bring the released costumes to the other titles. Since there are hundreds of costumes already available for both LittleBigPlanet and sequel LittleBigPlanet 2, it will take some time to re-package them up for the two upcoming games. This means that some of the costumes will be available at launch, while others will be released in phases.
There are a few exceptions however: The Assassin’s Creed costumes (the Ezio Auditore Costume from Assassin’s Creed Revelations and Ezio Auditore Costume from Assassin’s Creed II) or the April Fools Fragrance Costume (Hessian Sackboy Fragrances) won’t be ported to LittleBigPlanet Karting at this time, but all the other downloadable costumes will be available.
