>player is dumped into world after creating a party (of which the character creation is purely aesthetic as you can swap job classes freely) with no story intro
>as you fix the 8 crystals around the world you get extra jobs that work FFT style (you choose what order to acquire abilities in)
>you can generally approach the crystals in any order you want as soon as you locate the vehicles needed to reach them
>the world is a world of ruins and monsters where the last heroes failed, or at least the bad guy took the world with him when they "won"
>as you travel and fix things you slowly piece together who the original heroes and villain were, where the heroes are now, and what exactly was used to fuck up the world
