People in other nodes have reflected that Final Fantasy: Mystic Quest has no relation whatsoever to the Final Fantasy series itself, and is merely a lame attempt to cash in on a franchise by tacking the words "Final Fantasy" to an unrelated game, thus bringing attention to it. They are completely right.
They're not completely
right...Mystic Quest contained a number of Final Fantasy
references, or traditions so to speak. The most obvious one is the presence of four elemental fiends, and IIRC
they included the traditional stable of magic spells that are in every FF
game. I'm sure there are a good amount of other similarities, but...I can't, um, remember them. Yeah, that's the ticket. I can't remember them, and, uh, I don't have the time to play the game again...
(That lying at the end is especially transparent because one could probably beat Mystic Quest in a couple of hours.)
