I'm surprised at how many comments are criticizing the slow, contemplative nature of the song, saying it should have been more violent and big... I guess it's a common complaint with your music, people not understanding why your song is like that when all they did in the game was kill people, but I still just wish people didn't regard games with such shallowness as to ignore the thematic elements around which you build your songs.
This is one of my favorites of yours, I think. It's certainly one of your strongest lyrically, and perfectly captures Ezio's story. Brilliant, as always.
