Links hat is what definitely makes him. In other words, this time the saying "don't judge a book by its' cover" does not apply. The hat and tunic are what make Link a key character, just from the striking appeal and the ability to attract attention. The size of the Hat has increased over the years, and Personally, i think if nintendo make it any bigger, it would ruin Links entire look. Eventually if the hat keeps increasing in size, it willl be trailing on the ground, Nintendo definitely need to rethink increasing the size of the hat.
