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.

You seriously cannot be sued for having the Nose of Sooron. If you could be, you'd be infringing on copyright every single time you pressed the "Continue" button, and sent a post onto the forums, because you're using words and images somewhat similar to someone's copyrighted material somewhere - and yet claiming them as your own.
