Aimed primarily at purchasers of the collector's edition with its headstart, the extension will be credited to any and all accounts created before October 19th. Billing will be credited for another 30 days, giving a total of 60 days free time within the game world. The official announcement assured the community that the development team is listening to all the feedback received, and wishes to thank Final Fantasy XIV's players for their devotion to the game. Considering that the game has just seen its first pass of reorganization for the market system and a director dispatch on the game's future, it's a morning of good news for the game's players.
