Final Fantasy XIV (FFXIV) received a huge boost of new content last month with the 2.1: A Realm Awoken update, adding the new 24-player Crystal Tower raid, WolvesÂ Den PvP, new dungeons, extreme battles, and much more. This weekend Square Enix is giving both former players a chance to log in and try it all for free. Starting Saturday, January 11th, 2014 at 12:00AM PT, former players can log back in and play for free through Monday, January 13th, 2014 at 12:00AM PT. You can get all the details for the event on the FFXIV website.
