Ocarina of Time was my first LoZ game and my fave. Twilight Princess is defenatly #2 its a great game but theres just something about OoT that makes it really awesome....
My absolute favorite Zelda game is Skyward Sword. I love that it is a little bit cartoony (but not too cartoony like Ocarina of Time) and the storyline is fantastic. I frikin love this game and would recommend it to anyone who hasn't played it yet.
