Rofl!
Thats Exactly how Games are! you just want one little item but you have to do 50 things to get it!
You have to beat ganon, but ganon can only be beat by the master sword, Which requires you to get 3 stones from across hyrule, then you need the ocarina of time, to get the sword, then you have to complete the temples, but one temple requires the Eye thing, in which you have to beat the forest to be able to go back in time, then learn the song of storms, to go back to a kid to complete the well, to go back to an adult, to get the eye to go back to the dungeon to finish it, to go back to an adult to go to the illusion dungeon, but to get to the boss you need the hover boots, which are found in the final dungeon, in which you need the longshot to get, and the way to get the longshot is by getting the hammer rofl Yep thats zelda for ya!
