“Logging into the Same Account on both Windows and PlayStation 3
Customers who own a copy of FFXIV version 1.0 and wish to use their account on the PlayStation 3 version will need to purchase a copy of the PlayStation 3 version. It will then be possible to use your characters on either platform by tying your existing service account to the PlayStation 3 version upon launching it for the first time. However, please note that your account will only be able to log into one platform at a time.”
