Are you confused about the Zelda cause i am once i played ST i went nuts nintendo confuses me! Why? because ST happens 100 years after PH. Thats not all OoT once you finish the game there are two sides of the story, seriously Nintendo stop messing around with your fans.
To be honest i have no idea when the Zelda series starts well i think it started with The Legend of Zelda(or was it Link)i dont know.
Even though the Zelda series is confusing its still a fantastic game. Lets hope Skyward Sword is a good one!
