Oh, and just for fun (since we never hear about music in the dev journals), I LOVE the solo voice singing the GalCiv1 theme over the title screen. Kudos to your sound designer for cleverly linking the GC1 music to the new game.
I didn't react as well to the choral parts in the planet screen music (is it the planet screen music, or is that just where I happened to hear it?) , 'cause they seemed to be played on a keyboard. Maybe you'll have time to record with actual singers?
Anyhow, HOMM II (with its opera singing on the city screens) is among my favorite game soundtracks ever. And the work you've done so far on GC2 is pleasantly reminicent of it.
