Square Enix has temporarily halted sales of the digital version of Final Fantasy XIV: A Realm Reborn in a bid to combat long login wait times currently plaguing the MMO.

A post on Square Enix’s Facebook page, the company said A Realm Reborn's popularity had resulted in “extremely long wait times for users to be able to log in and play”.

“As a temporary measure, we will halt sales of Final Fantasy XIV: A Realm Reborn’s digital download products so we can accommodate all of those wishing to play," it said.

”We are working to expand our server capacity in the coming days. We sincerely apologize for the inconvenience this causes.”

On Monday, the game's director and producer Naoki Yoshida said that major updates would come to the game every three months.

Final Fantasy XIV: A Realm Reborn is out now on PlayStation 3 and Windows PC, and will be available on PlayStation 4 in 2014.
