Wagner, Tchaikovsky, Grieg, Rodgrigo, and so on. Truly one of the most pleasent soundtracks to listen that I have ever had the pleasure of listening to. It really adds a great deal to the atmosphere to be slugging it out in the suburbs of Moscow while the cannon sequence from the 1812 Overture is playing in the background. I am a bit of a classical music fiend, so I truly appreciate Paradox putting together such a wonderful soundtrack. I really liked the EU games soundtracks as well; here's to hoping that Crusader Kings carries on this fine tradition!
