Well the biggest thing LBP2 is doing, aside form the obvious gameplay, is the online social network. They need to REALLY push these guys making these levels. The thing about play, create, share is I cant make levels like this, but some Gems go hidden and unplayed due to the lack of organization.
Sony needs to push that in a big way because if they can show people the "developer" community of LBP is constantly churning out levels like this, and make it easy to hop on your iphone, PC or PS3 and queue up levels then when you get on LBP2 just play them it will be, and im not over-exaggerating, the real revolution LBP was supposed to be.
Also, media molecule needs to drop the weekly costumes and give monthly level packs too. I feel they were misleading in that area and relied on the community too much without giving them any support, especially with that god awful level select for usermade levels.
