I bought my Hobbit NIB second hand and was told when I called for warranty support that it wasn't covered because I was the second owner. That said, they did send me the replacement part that I needed(I paid shipping). I was told that because it was a small part they were willing to help out but if it was something expensive (they used a board as an example specifically) then I would be out of luck and would have to pay for parts.
I was the first owner to register the game.
