While Bravely Default: Flying Fairy isn’t a Final Fantasy game, it sure feels like one. Jump announced Bravely Default will have a job change system just like The 4 Heroes of Light and before that Final Fantasy V.
Jobs are tied to, surprise, crystals and one of the earliest crystals from the Eltania Empire unlocks three jobs. Monk, Black Mage, and White Mage are confirmed for Bravely Default.
The Nintendo 3DS game is slated for release in Japan sometime this year.
