I think I've heard the Legend of Zelda series called an RPG so much that it's been ingrained in my head, and I feel the need to defend the idea, apparently (since no one else seems to be. Devil's Advocate?) Maybe people see the series as having some RPG elements because of the items collected, and certain "stats"-like health and magic-increasing. Even your strength and defense get stronger because of "equipment upgrades." That might've been the same argument used for Super Metroid. But yeah; that is a flimsy argument. These "stat increases" aren't obtained the same way they would be in "traditional" RPG games; random battles! Anyhoo...
