Announcing the Launch Date of FFXIV: A Realm Reborn! (05/23/2013)
Players who have version 1.0 will not need to purchase FFXIV: ARR to continue playing on the PC. However, version 1.0 owners that wish to play the PlayStation 3 version will need to purchase a copy for the PlayStation 3. There are a number of points that you should be aware of should you consider purchasing a new copy of FFXIV: ARR so please ensure that you read the following before making a pre-order or purchase.
Players Who Own FFXIV Version 1.0
Players who own FFXIV version 1.0 will not need to purchase the PC version of FFXIV: ARR and will be able to download the FFXIV: ARR software for free.
* Details on downloading the FFXIV: ARR software will be provided at a later date.
Furthermore, users who have version 1.0 registration codes that have not yet been registered will be able to register them and play FFXIV: ARR on PC at the start of the service.
Players Who Own the FFXIV version 1.0 Collectors Edition
Players who own the FFXIV version 1.0 Collectors Edition will receive the FFXIV: ARR Collectors Edition in-game bonus items (Helm of Light, Baby Behemoth Minion, Behemoth Barding, and Coeurl Mount) for free. The in-game bonus items will be delivered via Moogle Letter when FFXIV: ARR launches.
Players Who Have Fulfilled the Requirements of the Legacy Campaign
Players who have fulfilled the requirements of the Legacy Campaign will be able to take part in early access and play before the official start of service.
Important Information for Customers Purchasing the PlayStation 3 Version
You will only be able to register one copy of FFXIV: A Realm Reborn for PlayStation 3 to a Sony Entertainment Network account. It is not possible to register or play two or more copies of the PS3 version on the same account even if you purchase additional software. Please note that only one Sony Entertainment Network account can be linked to a Square Enix Account.
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.
Collector's Edition Digital Upgrade Service
The Collector's Edition digital upgrade offers customers the ability to upgrade their standard FFXIV account to Collector's Edition status via the FFXIV Service Center website that is scheduled to be opened at the launch of official service, which then grants the in-game bonus items included with the Collector's Edition. Customers in possession of the Collector's Edition for either version 1.0 or A Realm Reborn will receive these Collector's Edition items without needing to purchase the upgrade.
* Characters that have already been created will be able to receive the items.
