In fact there was a recent message on one of the GalCiv forums that had a workaround for sound under XP and that worked for me as well (no music though). I have to admit though that I gave MOO short shrift during that point in my gaming life -- I was doing a lot of Mac work at the time and playing things like Strategic Conquest, Harpoon, and Dark Castle
while on the PC, I was into the RPGs: Ultimas, Might and Magic, and a little game called Doom.
I for one would be open to be convinced that this is as good a game as folk say, but I'd have to put wheels on my legs and start peddling real fast to get out of newbie'ville.
Be seeing you...
