Well, then Super Mario Bros is an RPG as well... One swallow does not make a summer.
Cherry picking my post doesn't show the context. Read it all, THEN digest it please. I said that there has to be archetype creation in so many words too. Taking one line and proclaiming that I mean something based on that one line out of context completely demeans the entire point.
So no, Super Mario is not an RPG unless Mario has different ways to play like fire mage, mushroom warrior, and dragon knight. And then I would go further to say there had better be a sandbox or open world of some kind, and plenty of lore to dive into along with a compelling reason to delve into it.
I was simply illustrating that you don't need convolution and clutter to express a RPG if role playing is the goal. As it really should be the goal of any RPG to first illustrate a compelling world, then fill it with life, and then introduce a dilemma to overcome as the player sets out on adventure; however, that character has to be your character -- not some cookie cutter model. Players interact with non player characters, and get embroiled in adventure. Progression obviously has to be there in some form. I have played many RPGs without an inventory management screen, and I have played some where there was no crafting.
Legend of Zelda games almost make the RPG cut in my book, but they miss the crucial application of building your own character or any sort of paradigm system to customize Link or Zelda.
