It actually hasn't officially been released in any form in the US, but it was originally a Famicom game, which would make it the equivalent of a NES game if it had actually been released in the States.

And eest's probably, right, unfortunately. Which is a shame, because the Job system arfing owned. Granted, it was also used in FF5, Tactics, Tactics Advance, and FFX-2, but the more games with the Job System, the better, I say.
