Stephi got Civilization IV for her birthday, and it ROCKS. We've been playing it quite a bit (it is dangerously addictive, though - one of the if not THE most addictive game(s) I've ever played... "One...more...round...*yawn*").
Anyways, it has an extremely cool intro song called "Baba Yetu" for the opening menu, you can get it here, courtesy of civfanatics: http://www.civfanatics.net/downloads/civ4/music/BabaYetu.mp3. Very epic, kind of mysterious, very catchy.
Well, I just found a page that explains the lyrics here.
And...it's the Lord's prayer in Swahili! That's friggin' cool! :)
