In My opinion, Music plays a major role in one's enjoyment of a 4X game, So i was wondering if we could have a system in which each game we get a unique piece of music, depending on one's nation/civilization choices(with each nation's unique music being added along the way) and factors such as millitarism, stability and culture. This would allow for a great number of different musical tracks, ensuring replayablily and plenty of combinations.
