An anonymous reader writes "We've all heard about user-generated content for games that have fixed toolsets — but this interesting piece on Develop has got me thinking about the idea of games production being opened to a community before development finishes. A new iPhone game (Aztec Odyssey) did that with its soundtrack; could someone do it with the game's art assets? Or level design? A great comment under the story says that LittleBigPlanet would have been more interesting if it was just shipped as a toolset with no pre-built levels. I'm inclined to agree!"
