* 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.
