Final Fantasy XIV is currently running a free return campaign, welcoming inactive players back into Eorzea through December 16th.
If you have an account and you own the game but took a break from playtime for at least 30 days, you are eligible to jump back in during the special event period to take a look around and see what's new. Re-login. Means that you can have access to 4 days of playtime for free.
So you can start anytime during the event time which runs through Friday, December 16th at 6:59 a.m. Pacific time. When you log into the game, the clock starts and the free play. Will end at 11:59 p.m. Pacific on the fourth day. So the four days includes the day and which you first login, so if you want to maximize your free time, you should log in early on the first day you can play.
There are some restrictions, including if you have more than one account, and any of them are currently subscribed, then you’re likely not eligible. Of course, they’re trying to lure people back into paying for subscriptions, so if you restart your sub, you don’t get extra time added to it if your free days aren’t up yet.
Still, it has been a while since the FFXIV team has offered free access for inactive players, so if you stayed away during the massive queues and want to see some of the additions like the Duty system expansion, some of the new side quests, and maybe even Island Sanctuary, then here’s your chance.
The most recent Letter from the Producer stream happened recently, and while the next major patch, series, 6.3x, isn’t due until January, there’s still a lot that has been added if you’re someone that has an account inactive long enough to be eligible.
