If you will excuse me, I'm going to be purposely obtuse for a moment. I disagree. The world is, in fact, quite enormous. The Eorzea that we inhabit is a small portion of a small island in a small archipelago, situated in a moderately sized continent on an earth sized planet. If anything, the relatively confined nature of the currently accessible portion of the world only goes to further illustrate how massive the world actually is. The Garlean Empire, by all accounts, spans 2 to 4 times again as much space, and is far from holding the entire world. A few expansions down the road, and I doubt you will be able to say the world is too small.
