I'm not saying make it exactly like the linear style game that has an absolute ending like all the other zeldas but it seems to me that zelda games allways like to have side quests and there seems to be alot to do in the universe so i dont think much would change, you would have quests and missions ect side quests and stuff but their just wont be a glorius amazing you defeated ganon finish. Majoras mask played with the concept of becoming different races with the masks so a non linear zelda game that allows you to be any race you like isnt so far from the zelda ideas used in the past. the only new thing would be all the other people around the world playing in the same zelda universe and interacting.
Nintendo would prolly put limits on this though :( they may not allow out right killing of each other, but they may associate safe and unsafe zones, like night time is dangerous so dont go outside during the night unless your powerful or have certian areas of the map such as forests where your allowed to kill and take peoples items
its a possible concept that would work and it wouldnt really change anything that hasnt allready been toched on a single player environment
If at first you don't succeed, you fail
