If you want to know what it's going to be like to party with others in the upcoming Final Fantasy XIV: A Realm Reborn, Square Enix has released a new developer's commentary trailer showing off just that. Here, you will see what it's like to join up to explore a dungeon and learn more about job roles. This should be helpful for those new to MMORPGs, as the phase 4 beta starts this weekend with early access beginning on the next.
