Limbo is an amazing, atmospheric puzzle game involving a boy’s journey through a dark landscape of terrible insects and abandoned factories. It earned critical acclaim, and turned out to be a decent game, too. When Limbo’s developers went looking for a publisher, they came to Sony. Unfortunately, Sony demanded all rights to the game and its intellectual property, that is, the IP rights, which would mean the people who created the game and its world would own none of their creation. The studio, Playdead, walked and went to Microsoft. Limbo has since sold over one-million copies. There might be a lesson in this. Edge Online has the story.
