What I am saying is that "copyright" laws, rely on "copying". 30% change is enough to be considered original content. It's not so hard at all to change 30% of the creative content, and to not reuse any graphics that are under copyright.

It's not quite that simple (when is anything to do with law that?) Copyright law also has the concept of "derivative work" which can include wholly new works, but which are based on existing, copyrighted work -- such as fan-fiction, user-made mods, movie versions of books and so on.
Look into the "Hobbit" lawsuit of the Tolkien Estate vs. TSR over D&D.
