To celebrate the new patch on July 8th
MMO subscribers often come and go, no matter how much they love the game. Whether it's real life responsibilities or a momentary retirement until new content comes out, there's a lot of reasons people may unsubscribe. With Final Fantasy XIV: A Realm Reborn's upcoming Welcome Back campaign though, anyone will get a chance to log back in and see what's up before re-upping their sub.
The campaign is running from July 11th until July 14th -- Square Enix hasn't detailed whether or not you can access the game without buying it.
