Jobs and classes of course appeared in the previous games in a manner of speaking, but at the core of the combat and strategy of FF3 is the player’s ability to unlock, play as and switch between a wide variety of jobs - all of which have unique abilities.

Each of the first three FF games introduces something that’d become fundamental to the rest of the series as we know it today.
