This is all going to be “great gameplay” rather than “great story”.
If you have a way to play 3DS games and a tolerance for punishment in your JRPG dungeon crawlers, the Etrian Odyssey series has some of Yuzo Koshiro’s best work.
Finally … Monster Hunter is an incredibly fun and addictive game series, and though it doesn’t center the music quite as much as a typical JRPG does, it’s got some great stuff. I particularly like the soundtrack of MH: World – although the newer game MH: Rise tried something new with its mostly choral arrangements, I think they are not quite as memorable overall.
Arena battle from Monster Hunter: World (it’s particularly impressive the way this theme, the small-monsters arena battle theme, and several of the town themes reuse the same melodies in different arrangements)
