I really, really, prefer having a big continent/archipelago fully-fleshed out (and with a reasonably realistic scale, like this one) rather than having an entire planet for you to explore.
The latter makes the universe the game takes place in very small, and even goofy and lazy (only five towns per planet or so is rather ridiculous). It was alright in previous FFs (VIII and IX's worlds are some of my favourite fictional universes), but they should stick to this method for now on.
XII had something similar and even though the game was heavily divided into sections, the world felt alive and huge, unlike the previous ones. And if this one is as seamless as it looks... well, you know what.
I'm loving the look of the world, and if we take Accordo into account, we can see how big the scale is. Now show me dem cities and towns, pls. Really excited too about how diverse the game will be. I hope we get our (well justified within the world location) doses of snowy, desert, beach, etc areas.
