雖說我發現這個DLC時，聖誕節其實已經過了頗久，但我還是滿喜歡這首歌的...
CK2跟EU4都可以免費下載這個DLC，也有mp3版本
You rule the world with might and grace,
And make your nation grow,
People and cultures, united by your hand,
A historical paradox
A historical paradox
A historical, ahistorical paradox.

所以本DLC只有音樂嗎?

感謝大大提供資訊~

這是P社的聖誕禮物。BTW, falalalan是EU2的一首famous/infamous歌曲。
