Final Fantasy XIV, and you subscribed for a while, but you stopped subscribing before the first major patch. Maybe you were tired of waiting for it, maybe you had other things to play, maybe you were hoping the game would go free-to-play by now. Whatever the case, you can pop back into the game for a weekend and play around with all of the patch's additions, assuming you can get all of that out of the way in 48 straight hours.
Starting on Saturday, January 11th, at 3:00 a.m. EST, former players whose accounts are inactive will be able to log in and play the game absolutely free until Monday, January 13th, at 3:00 a.m. EST. Nothing special is required to try out the patch; just log in, download, and go to town. The patch features beast tribe daily quests, new endgame dungeons, the Crystal Tower, and additional main scenario quests following the conclusion of the story.
