* MarketBasedTitle: The original release and the UsefulNotes/GameBoyColor re-release were titled ''Dragon Warrior'' due to [[TabletopGame/DungeonsAndDragons TSR]] holding the trademark to ''Dragon Quest''. Since Creator/SquareEnix has subsequently acquired the trademark from them, any future release will bear the ''DQ'' name.
* RemadeForTheExport: The North American version of the game received a graphical facelift as well as a battery-backed save instead of a 20-character long password system used in the Japanese version.
