The inclusion of backward compatibility for Xbox One presents a unique opportunity for FFXI Online.
I am aware that the idea is to shut down the servers for Xbox360 next year, but that decision was made before Microsoft's surprise announcement this year at E3. Since Microsoft is footing most of the work for making titles play on their new console, why not cancel the shut down for Xbox360 and instead rebrand FFXI Online for release for XboxOne players? Add a free download to the Microsoft store, and you might attract all the players hungry for good MMO content in an otherwise limited selection.
Keep the 360 servers going and use this opportunity to Bring FFXI Online to a current gen console for free!
