A story and crafting have nothing to do with being massively multiplayer. They are more indicative of being an RPG. Skyrim is not an MMO, but it has both of those. Those are the RPG elements of the MMORPGs that you are thinking of (most likely WoW). The other features are spot on though. It would be possible to have an MMO fighter or an MMOFPS. I wish Destiny were an MMO. As it stands it is a shared, closed world (who can really defend it as "open" with all its invisible walls and death barriers) multiplayer FPS with RPG elements.
