And if you're after a fanservice free-for-all battle, look elsewhere, as FFXIV isn't that. Play Dissidia or FF All The Bravest if that's what you want.
Mainly the thing that probably lends itself to most people thinking that it even could be the same world is that it essentially has the exact same 5 primary sentient races, and some of the same beastmen like goblins and such. Still, there are a lot of similarities, maybe they are different planets within the same solar system perhaps?
