Ocarina of Time will always be my favorite Zelda game - (of course, it will come to the test when skyward sword comes out, BUT), and here's why.
Ocarina got me inspired to draw again during Middle School. I didn't always... draw all the time like I do now. Anime had gotten me stuck in a rut, and for some reason, Ocarina got me to stop all that nonsense and got my artwork going in a direction to where I'm happy with now.
So thanks Nintendo and the Zelda team, for making the greatest game of all time - it was both an inspiration and an experience I'll never forget.
