A creation of any sort needs a base a structure if you will. How do you build something when you don't know how to start. You have to take what others have done(not steal merely as inspiration)and reinvent it from your own prespective. Or you can take the driven approach and go out on a limb and create what u want instead of what u know is good. I would like to see less of the latter of the two and more original, ground breaking anime/manga.
