-I have digital deluxe. Can't find soundtracks at steam music or anywhere else.

-How can I turn classic turns on?

For the music, we are looking into why some of you do not seem to see their music in steam music. 

what do you mean for classic turns? 

I guess he means the standard system (à la Civilization). You play, then the IAs (or the other players) do, instead of simultaneous turns.

The whole game is designed around that, so it would be quite complex to remove.

I hope it will not be too much of an annoyance for you.
