It sounds pretty serious, and we guess it is, given the fact that A Realm Reborn is almost upon us. To mark the occasion, Square is throwing open FFXIV's gates to all account holders regardless of whether or not they possess an active subscription. Beginning early tomorrow (3:00 a.m. EST, to be exact), you can log into FFXIV and say your goodbyes to its current incarnation. Don't delay, though, as the opportunity expires along with the original servers early Monday morning.
Be aware that "any progress made will not carry over to A Realm Reborn."
[Thanks to Lior for the tip!]
