Not bad for the first handheld RPG ever
TFFL seems like a standard RPG with four people in your party walking around and running into constant random enemy encounters. This is true, but from there the game really wanders off the beaten path, creating its own rules and methods, like weapons that have a limited number of uses (which I despise). I won't get in to all of the details; just trust me when I say it does not play like Final Fantasy. A lot of the gameplay elements were actually very innovative at the time. The option to use monsters and mutants in your party are a good example of this.
The graphics are very primitive and it has a poor story, however, the music and sound was all done by Nobuo Uematsu and is pretty good.
I would not recommend this game to anyone but the most devoted Square fan. This is the first in a long running series and should be experienced to see its RPG roots; just ignore the 'Final Fantasy' in the name and consider it "SaGa 1".
See you again!
