Square Enix just released a very long Final Fantasy XIV A Realm Reborn trailer that easily explains some of the games unique features. Unfortunately, the voice over dub for the promotion trailer is currently in Japanese but it should give you guys a general idea of what is in store for you. The thirteen minute long trailer goes into detail about the armory system, character creation, crafting system, job system, content(party?) finder, and so much more. Worth checking out when you have time!
