While DQ until it went MMO reflected a land of little change and the quality was retained, Final Fantasy has been all over the board especially once they went to Sony and in particular from 10 onwards. They have their moments and stuff, but despite the better tech I for one felt the music has lacked in them at least for being memorable if anything else. Personally I think the era of the 16bit stuff has the most stand out music that really just grabs you in the Square games from Final Fantasy titles, Secret of Mana or even Mario RPG. Enix in their own right either stuff they made or just published(Quest--Ogre Battle) were in every way just as special and memorable.
Do any of you have any particular pieces from the 20th century stuff or even the refined more recent re-releases you prefer and have any reasons why?
