Oh, I've played Zwei II: The Ilvard Insurrection. Its music is absolutely fantastic. The game is called "Zwei!!" because the gameplay has you constantly toggle between two protagonists with markedly different fighting styles, entirely referencing the gameplay with no intention to "skip" "Ein." I couldn't tolerate the first one, but give the second a go sometime if you ever come across a copy! The band jbl behind Falcom is truly incredible; you can hear the main theme manifest repeatedly in so many diverse, cool ways throughout the soundtrack.
