It's often been reported that Hironobu Sakaguchi called his game "Final Fantasy" because he intended it to be his last game before leaving the industry. It's also been reported the name was chosen due to financial difficulties faced by Square at the time that this could be the last game they could produce. However in truth the developers were looking for a word to compliment the fantasy theme of the game. The criteria was that the title needed to be easily abbreviated using the Roman alphabet and that abbreviation needed to be four-syllables. Using the word "Fantasy" was an obvious choice, given the game's genre. After initially considering Fighting Fantasy but finding out the name was already in use, they chose "Final." The abbreviation "FF" (efu efu in Japanese) fit the four syllable requirement.
According to Sakaguchi, "Really, anything that started with an F would have been fine for the title."

In the original US release, in the elven village, there are a trio of tombstones north of the Inn. If one reads the second tombstone, it says "R.I.P. Erdrick". Erdrick is the name of a legendary hero in one of Final Fantasy's contemporaries, Dragon Quest (USA: Dragon Warrior). This was placed as a joke, mentioning its competition. In all Japanese releases as well as the US Playstation release, the headstone reads "Here lies Link", a reference to the hero of Nintendo's Zelda Densetsu / Legend of Zelda games.
The line "I, Garland, will knock you all down!" was not in the original Japanese version - it was an old NES mistranslation that went down in history due to its laughable nature. Despite it not being accurate to the original Japanese version, this quote is deliberately left intact in all American ports of the game.
In the original version of the game available for the Nintendo Entertainment System and Famicom, a secret slide puzzle game can be accessed by boarding the ship, holding down the A button and pressing the B button 55 times. This was kept for the Virtual Console port and some remakes.
