I'm talking about FF3j, for the NES.

*sigh*

FF2j, FF3j, and FF5 were never originally released outside of Japan. In order to avoid consistency errors, Square of America decided to call FF4 (the one with Cecil and Cain) FF2, and to call FF6 (the one with Terra and the espers) FF3. Of course, the confusion started when the released FF7 and didn't decide to call it FF4.

FF2j was released as part of Origins, and FF5 was released as part of Anthologies. FF3j has only been released on the NES, and only in Japan.
