Just like the title says, Is the Legend of Zelda series an RPG series?

Legend of Zelda
Adventure of Link
Link to the Past
Link's Awakening
Oracle of Ages
Oracle of Seasons
Minish Cap
Four Swords
Ocarina of Time
Majora's Mask
Windwaker

Am I missing any? Remakes don't count....

A friend and I got into an argument and I figure a Poll on an RPG forum would prove who is right. I will not say what I believe until a few replies are made.
