Final Fantasy
Because the previous two installments of the "Final Fantasy" series had not been localized and released in North America at the time, "Final Fantasy IV" was distributed as "Final Fantasy II" to maintain naming continuity. This remained the norm until the release of "Final Fantasy VII" in North America (after the release of "Final Fantasy VI" under the title of "Final Fantasy III") and subsequent releases of the original "Final Fantasy II" and "III" on various platforms. "Final Fantasy II" has since gone under the title "Final Fantasy IV".
