A work colleague posted this
saxophone cover of Decisive Battle II from Octopath Traveler. It's really good! And I have never played Octopath Traveler.
I always think Decisive Battle as being the name of
this song from Final Fantasy VI, but as he pointed out, there turn out to be many
decisive battle themes in JRPGs. And they all have a certain tempo and up-front bass line and arpeggios kind of thing going.
