that makes no sense. have rotating, less dramatic battle themes and some that are much different in tone for boss battles, uematsu
of course, he might just be saying this because the way it was done was his only option, on the orders of a clueless director/producer.
i think it's important to be mindful of music use in games, but he didn't think past his nose to realize that people play final fantasy games for 40+ hours and that people are well aware when they've hit a dramatic moment...yes it would be bad if a boss battle used the same battle theme as regular enemies, so uh...just don't use the same theme.
More importantly, as a musician, he should know that that is too fucking long to be listening to the same 2 minute clip over and over, with the occasional break for a boss battle every 10 hours. Eventually, I'm just ignoring his work because I don't care how nice a battle theme is, it's not nice after hearing it loop for 10+ hours. It's literally absurd how much you have to hear the same music in these games and for absolutely no reason, nowadays.
I'm guessing a lot of these composers have been hamstrung in the past with cart size and disc size limits, forcing them to use one battle theme. Then, in typical rigid japanese fashion, they just plain never thought to ever change it, once it became possible to be more creative with use of music, thanks to larger disc sizes. Of course, Nocturne proves that there has been no reason to use music as if it were an 8 or 16 bit game since last gen. But we saw XIII basically use the same theme to death and i'd bet my nuts that XIII-2 will do the same thing. It feels a bit condescending, like they just don't care to fix this one obvious flaw because fans don't care/notice.
