After the universal negative reception of the PC release of Final Fantasy XIV, Square Enix decided to revamp the whole game with Final Fantasy XIV: A Realm Reborn. The game re-works every element of the original, including the character creator.
First, you choose a race, like you did before as well, but this time you can choose either sexes for all races.
You can choose classes for your character after you select the race, and with the release of A Realm Reborn, there will be a new Arcanist class along with a new job, Summoner.
Alpha tests are being carried out to try out some of the new features. You can register for the alpha test here.
