In 1994, in an incredibly short-sighted decision, Final Fantasy VI was released in the USA as "Final Fantasy III" because it was the third game to actually get released here.

This was before the internet--we couldn't easily look up that there were three other games in Japan at this point.

That one decision created decades of misunderstandings.

Square said "screw it" and called Final Fantasy VII by that name worldwide, to end this.

EDIT: Final Fantasy IV was previously released here as "Final Fantasy II" as well. Its translation was so poorly received (aside from one infamous line) that it led to Square looking elsewhere for localization help, which resulted in them hiring Ted Woolsey.
