For those not in the know, FFV has an event called the Four Job Fiesta, a charity thing where you are assigned four randomly selected Jobs at the start of the game and have to complete the game with those jobs and none other.

Now, I hear in FF3NES, only Sages and Ninjas are worth anything by the end. But in the Remake, every Job is viable till the end. It seems like it is tailor-made for this sort of thing. I would do it, if it existed.
