Ask people to name their favourite Zelda games and they'll invariably rattle off console titles. Link to the Past, Ocarina of Time, Majora's Mask, Wind Waker. The handheld Zelda games, most of which are excellent, are often left off the list, which is a little unfair.
Look, I know if there was a list of the top 100 toughest bosses in video gaming, Minish Cap's Vaati wouldn't make the cut. There are NES games, or games that end in "Souls", that are way harder than any handheld adventure Nintendo has ever conjured for Link.
