Intricate pieces would be very welcome indeed. Given that XIV is an MMO, I think SE will keep in mind that it is meant to have a certain enduring quality about it, and hopefully the music will truly reflect this.
I dunno, I didn't think FFXI's music was too
boring. It had charming melodies and helped set the tone quite nicely for diverse areas, especially if you paid particular attention to it. I just...don't know if I want any more electric bagpipes.
I also think it'd be really cool if the boss/big fight tracks were more rock/metal than orchestral.
YES. FFVII: Advent Children's climactic battle scene with the metal-ized One Winged Angel. /fanboy. Anywho, given that FFXIV's setting will be more futuristic than FFXI's somewhat medieval setting, I think we can certainly expect the music to be more rockin' when appropriate. It would definitely be a nice change of pace from the overused chorus singing in Latin we see in too many games today. (True, FF has been doing that for a while, and they do it well. I just want to see other stuff too.)
