Is it cheating to choose an entire series rather than a single game? If it is, I don’t really care. The Final Fantasy series has always just sounded fantastic. A lot of this is down to the composer who worked on most of these games, Nobuo Uematsu.
The huge, orchestral scope of these soundtracks are inspiring and uplifting. Rather than go on about them, I’m just going to link a few highlights from across the series. Below is one song from each title in the main series. Bear in mind as you watch, that the original titles were on the NES and SNES, and so are technically limited. If you want to hear more technically impressive songs, maybe try starting at the entry for Final Fantasy VII.
Main Theme ~ World Map (Final Fantasy)
Chocobo Theme (Final Fantasy II)
Megalopolis of Saronia (Final Fantasy III)
Parom and Polom (Final Fantasy IV)
Dear Friends (Final Fantasy V)
Kefka (Final Fantasy VI)
Aerith’s Theme (Final Fantasy VII)
Eyes On Me (Final Fantasy VIII)
Prima Vista Orchestra (Final Fantasy IX)
Suteki Da Ne (Final Fantasy X)
Opening Theme (Final Fantasy XI)
Infiltration (Final Fantasy XII)
Eidolons (Final Fantasy XIII)
Garuda’s Theme: Fallen Angel (Final Fantasy XIV)
I could go on and include all of the spin-offs and whatnot – Final Fantasy: Crystal Chronicles has a great soundtrack – but I think 14 tracks is enough to be going on with. Amazing soundtracks which push the boundaries of game music.
