It appears levels created in the LittleBigPlanet BETA will not be compatible with the full game. So far, 1000 levels have already been published but it looks like everything will be lost.
To quote: I interviewed Leo Cubbin, one of LBP’s producers, today. I asked him what will happen to all the user created content when we replace the Beta version with the full game. The answer was what I feared: everything is lost!
I don’t know about you guys, but I treasure my levels and I don’t want to just lose them like that, so I tried to argue that they should allow us to move the content into the full game. Leo replied that maybe they’ll convert the best levels, but they can’t convert everything.
It looks like noone expected such a big response to the Beta version. So far, 10.000 people have logged in, and 1000 published their own levels. I guess a lot more are still working hard on those levels before they hit the publish button. And all that content will be lost soon…
