The launch of Final Fantasy XIV: A Realm Reborn has been somewhat marred by heinous server waiting times and, in a number of cases, sheer impossibility of play.
So Square have decided to stop selling the game until hey can sort out their backend.
Here's the official statement courtesy of the Square-Enix Facebook page:
Due to the overwhelmingly positive response to FINAL FANTASY XIV: A Realm Reborn, we are currently experiencing 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. We are working to expand our server capacity in the coming days.
We sincerely apologize for the inconvenience this causes.
We'll try to let you know when you can pick up the game once more.
