Guys your missing the point. LBP gives you a choice too play free user/dev created/dev levels or design your own. Whether you charge for them later probably depends on the quality of the said level that you design.

You're missing the point why this sucks:

1. People like money-- that means people with good levels will want to charge for their levels and people won't want to buy levels.
2. They are going to have to enforce some sort of Big Brother watch to make sure people just don't copy buy levels.
3. You will not be able to edit user created levels (what I was interested in).
4. Every user will have access to every shit level and levels of up and coming people who are still free.  If you want the actual good levels you will have to pay because as I said in point #1, they will make you pay.
