@Fawful: the final bosses of all three Zelda CDi games died after one hit.
and Majora's Mask is just another game until you look really far into it. that includes completing the Bombers Notebook and getting the Fierce Deity Mask. (WARNING: the Anju and Kafei mini quest can cause extreme frustration, but it feels great to complete it.)
you also need to "read between the lines" at times, especially at the Stone Tower. If you look really closely at parts of the Stone Tower, you might start to figure out why Ikana is cursed.
Majora's Mask was one of my favorite games for sidequests. Getting all the masks, trading the title deeds, bombers notebook. It got pretty extensive in that game. Although no sidequest compares to the biggoran sword (however you spell it)
