I can agree with this. Not only did it start off the whole fantasy RPG stuff (including boss battles, health, magic meters, etc etc as you mentioned) waaaaay back in NES days (or was it Super Nintendo? i forget), but it was revolutionized with Ocarnia of Time on the N64. They made that sh*t 3D! xdIt's Zelda and it's not even close. Everything in all of the games everyone else has mentioned came from Zelda: Inventory screens, targeting systems, tons of RPG elements, puzzle solving, boss battles, Health and magic meters, and platforming.
