Here is a song from one of my favourite games
Rome total war's
Forever
It plays at the end when you finally beat the game. You feel victorious, proud, you have vanquished your enemies, slaughtering all who got in your way. You are a god among men.. and then the credits roll, and you hear this music. You hear the song of the wife of the fallen soldier. You are brought back to earth, and face the knowledge of the untold pain and suffering you have caused in your rise to power.
Extremely deep for a game.
