On a Facebook post, Square Enix explains they have temporarily stopped people from buying online copies of Final Fantasy XIV A Realm Reborn. They cite overwhelming demand exceeding server capacity.
To be specific, the high demand from fans has led to extended wait times for players who have already bought the game, and Square Enix simply needs to manage it. Digital sales of the game will remain closed until they can get more servers up and running. Some fans are already speculating the game’s servers may have crashed. However, it’s important to note that unlike the Diablo III and SimCity launches, A Realm Reborn did not create a huge online uproar over crashed servers. At the very least, their launch has not been as disastrous as it was for those games.
The comments on the post indicate a mixed reaction. Many fans are happy with the game, and are either defending Square Enix for something they say is now par for the course for every MMORPG launch, and/or telling fans to calm down. However, there are also some complaints about how Square Enix have handled the issue. Some players complain that there are many players who log in and stay online all day even when they are not playing, and Square Enix should implement a 15 minute automatic AFK logout or a similar penalty. Other fans are claiming Square Enix deleted an earlier thread where they first aired complaints, and that they have handled their customer service badly. Again, there are no complaints about crashed servers, and, as many point out in the thread, there is nothing but high interest in the game.
