Final Fantasy XIV: A Realm Reborn is not a fresh new game, it is a three year old game being rebranded and resold with a different name. The fact that our servers and characters from 1.0 still exists proves this, the fact that the core mechanics have only barely changed also shows this. They changed the UI, tweaked the mechanics to make them enjoyable, but it's not a brand new game, it's just an expansion.
This is no different than when World of Warcraft came out with the Cataclysm expansion to draw in more new subscribers.
