Odd move by Nintendo, surely it's not doing them any harm to leave it alone if the creators agree to keep it non-profit?

Two brilliant Lord of the Rings fan films have been made, and the Tolkien Estate has allowed them to be distributed for free on the internet, and both are magnificent for fan films. Nintendo should take a leaf out of their book and encourage this sort of thing rather than unleashing the hounds on fan productions like this, crappy or not. (If you're a LOTR, I recommend watching those films by the way - Google "The Hunt for Gollum" and "Born of Hope" to find them; the former takes place during the Fellowship of the Ring as Aragorn tracks Gollum before Sauron can find him, and the latter is a tale of Aragorn's parents and the Rangers. Good stuff.)
