To celebrate, Final Fantasy XIV is hosting a free login campaign that starts Friday, February 27th, at 3:00 a.m. EST and runs through Monday, March 9th, at 4:00 a.m. EST. You’ll need to have previously purchased and registered your copy of A Realm Reborn and have an inactive account to be eligible. Alternatively there’s a 14-day Steam demo.
The four million figure represents a healthy increase from the 2.5 million reported by Square in December, 2014.[Source: Lodestone; thanks Kev and Wratts!]
