WOW, Garcius' Melody in particular just blew me away! I'm listening to it again now. Very very good composing and nice restraint through the whole piece also. I love the lilting, floating melody and bits of loneliness and remorse that is dropped in sparingly too.
I know you said FFTA but I am picking up heavy Chrono Trigger vibes from this also. Speaking of FF, etc if you haven't listened to Emerson, Lake, and Palmer before you definitely should. Start with their self-titled and then listen to Tarkus.
