Hello, this is FINAL FANTASY XIV: A Realm Reborn Producer and Director, Yoshida.
The maximum expected population limit is nearing for each World, and unless the current World simultaneous connection amount decreases, we are unable to open release the limitation.
In case we do release the limitation, there is a high chance that the corresponding World will crash or cause issues, and we are thinking that it will be difficult for us to release it for a while. We please ask you to consider playing in a World that has a low limitation.
We are sorry for any inconvenience that this may cause and ask to continue with your cooperation.
