Media Molecule co-founder Alex Evans has told GI that the "user" part of LittleBigPlanet's user-generated content is just as important as the content itself.
"Creators are just as important as levels, so as a creator we have world rankings of who's the coolest creator, or who's the coolest community-minded commenter or sharer," he said.
"So you can be a little bit competitive if you want to be, and you'll have feeds of photos of you - levels that you've been in, photos people have taken of you. Then we take it even further, like Facebook. In any photos we know what kind of Sackboys were in it, who they were logged in as, so we put a box around their face which you can click and go and see that person.
"So if there's a cool level with a guy wearing an awesome costume, you just D-pad up to him and hit X, and now you can see his levels, his favourites."
There's loads more "blue sky" thinking through there. The game's out at the end of October.
