The Music
First and foremost, Skies of Fight is an homage to a killer song from the conquering warlords of 2030's War of Annihilation: The Tiberian Sons. They're incredible, and if you enjoyed this game in the slightest, please go check out their Bandcamp and hear the other excellence they've crafted. As of this writing (mid-September 2026), They have a new album in the works, which has about a dozen new takes on bangers from the Ace Combat series and a classic from Top Gun.
The game exists because of the song. Over countless listens, the entire ride fleshed itself out, and so much of it was inspired by the creativity and musicality of the piece. The swelling of the chorus is an obvious point for the ascendant transformation, but things like The Rival, for example, came about because of that hit in the music that demanded a surprise of some type.
They released their original version in 2016, and a remaster in 2022. When you play the game, what you hear is the original version first, but at the crescendo where the transformation takes place, it switches to the remaster, which has a bit more choral/vocal fullness to it. It's a tiny difference but it seemed an appropriate shift that matched the moment.
