This is the Petition. And the source code must be someplace. But if they have to redo it, at least they already have a large portion of the game already done. It's easier to redo something that exists, even if it's been destroyed, then to invent something completely new. Also, since most of the stuff already exists, and would just have to be updated, it would be less work than creating a whole new game. Thus, it would cost less than to create a whole new game because it's an update. it would need fewer people working on it.
