Square Enix has announced that they've now reached four million registered players in Final Fantasy XIV: A Realm Reborn. A massive number. If you're one of them, but don't play anymore, today is a good day to get back into it. To celebrate the four million player milestone, Square Enix has made it free (starting today and until March 9) to log in and play with your old characters, or to try it out if you've never played before. This also makes it possible for you to try out the massive update (which includes, amongst other thing, the Gold Saucer from Final Fantasy VII) that was launched earlier this week.
