i think that up untill now, every zelda game has been pretty much the same (virtually) WW and MM brought something completely new, are you people scared of that? do you want to colect three gems, rescue seven sages, find out your are the hero of destiny, and defeat gannon in every game? that will get boring, WW added alot to the story, it will also allow the gamemakers to come up with innovative game mechanics,
in other words, just be happy with what you have, if you have such a problem with what they are doing with the zelda series go buy a sexbox and play shoot um up games till your eyes bleed
