It has since continued across multiple platforms, from the Super Nintendo Entertainment System to the PlayStation 2, and like the Final Fantasy series, the story in each SaGa game is independent of its counterparts.

The music of the original series was composed by Nobuo Uematsu, Kenji Ito, Ryuji Sasai, and Chihiro Fujioka.

Uematsu has stated that while SaGa 1's music could be made of better quality, the emphasis was on enjoying the game, and not solely its appearance or sound.

[4] The Game Boy's sound hardware was different from that of the Famicom, which Uematsu was used to composing for at the time, with new stereo and waveforms and only three notes; as a result, Uematsu struggled with deciding how to work with these, developing new themes for the music in the process despite SaGa 1's director Akitoshi Kawazu's desire to have the music be in the same vein as Square's preceding Final Fantasy titles.

He credited the excellence of the soundtrack to the limited audio resources the composers had to work with on the Game Boy, which in his opinion forced them to be more creative in their compositions.

Surrounded By Enemies", "The Whereabouts of the Fierce Battles", "The Goddess of Destiny", "Twilight Courtesan Journey", and "Militant Meat".

It includes music from the original game remixed for the DS by Ryuji Sasai and Kenji Ito, as well as new tracks composed by the two.

[12] The soundtrack was well received by Patrick Gann, who noted Ito's ability to push the audio hardware of the Super Nintendo to its limit, with various sound effects that were beyond what other similar games were using.

Eve C. of RPGFan disliked the album, calling it a "disappointment" and citing that in her opinion it did not sound French, that many of the tracks were "boring", and that the arrangements were "mediocre".

[13] Dave of Square Enix Music Online mostly agreed with Gann, calling it "extremely diverse" and full of "inspired arrangements", marred only by a couple of disappointing tracks.

[16] The album was appreciated by reviewers such as Dave of Square Enix Music Online, who called it "definitely worth listening to" and applauded the wide variety of instruments as well as the "thought" that went into the tracks.

When Ito arranged the music of Romancing SaGa 1 for Minstrel Song, he felt that because of all of the fans who had played the original game and the change in audio hardware from the Super Famicom to the PlayStation 2 he did not want to simply re-arrange the pieces, but instead tried to "re-make" the soundtrack into something which could stand on its own from the original soundtrack and the game.

[23] Chris Greening of Square Enix Music Online agreed, saying that it exceeded expectations and was Ito's "finest work to date".

[27][28] In the liner notes for the soundtrack album, Hamauzu explained that when he began the project he felt pressured to compose music in the same vein as the previous soundtracks in the series, but in the final months before finishing he decided to abandon any preconceived notions of what the music should sound like and instead to "express [his] own unique character".

[33] Nathan Black of Square Enix Music Online also highly praised the album, calling it "excellent" and saying that it "amazed him".

[36] Aevloss of Square Enix Music Online said that each track was "of a consistently high standard" and that the album as a whole was better than the original soundtrack, which he held to be "very impressive".

Hamauzu said that the tracks that used live instruments almost exclusively were the ones that were "Latin" in style, such as "Anxiety towards a Wonder" and "Battle Theme IV".

Hamauzu described the major differences between this soundtrack and his previous works as being the result of changes in technology, which allowed him to include a wider variety of musical genres as well as "ample" acoustic instruments.

[28] When Hamauzu thought to use a song in the soundtrack, he decided to cast Mio Kashiwabara as the singer, despite having only met her once at the Tokyo University of Art festival two years before and never working with her.

[40] It was well received by critics such as Jeff Tittsworth of RPGFan, who applauded its variety, saying that each track had a "distinct feel" even as the album as a whole felt "cohesive".

[39] James McCawley of RPGFan agreed; while he preferred the sound of the second disc, he felt that together they created a stronger album which reflected "the split sides of Hamauzu's musical character".

[39] Chris Greening of Square Enix Music Online also enjoyed the album, calling it "an accomplished piece of experimentation that is also often satisfying on an emotional and melodic level", though he added a caveat that if the listener did not enjoy electronic music, they would find the album "often wonderful but also hugely inconsistent".

All three tracks on the album were composed by Masashi Hamauzu, while "Unlimited SaGa Overture" was arranged for orchestra by Shiro Hamaguchi and "Soaring Wings" was sung by Mio Kashiwabara.

It was published by Square on December 12, 2002, with the catalog number SQCD-30001, and was included with the limited edition version of the game in Japan.

[45] The set was published on August 26, 2009, to coincide with the 20th anniversary of the release of the first SaGa video game with the catalog numbers SQEX-10145~65.

[44][46] Patrick Gann described it as an excellent collection that was worth the purchase for anyone who wanted to own the entire set and did not already have most of the albums, though he noted that as it included multiple composers and styles the compilation box would not be justified for everyone who liked just some of the music of the SaGa series.

[44] "Overture" from Romancing SaGa Minstrel Song was performed at the "Press Start -Symphony of Games- 2006" concert in Tokyo on September 22, 2006.

The FILMharmonic Orchestra and Choir was conducted by Andy Brick and featured Jaromir Klepac as the pianist; they performed "Feldschlacht V", or "Field Battle 1".

[49] Selections from Piano Pieces "SF2" ~ Rhapsody on a Theme of SaGa Frontier 2 were played in a concert in Paris of Hamauzu's work on May 22, 2011.

The compositions from Unlimited SaGa were rewritten by Tadaomi Idogawa as beginning to intermediate level piano solos, though they are meant to sound as much like the originals as possible.
