Some pieces from games bring a tear to my eye because I remember the moment in the game, or I just think the music is freakin' amazing whether it's in a game or not. I love music But anyways, it could also remind you (like FF6 does for me) of a time when your life was much simpler. You had less worries in your life and so, when you see the game, or hear the music, it reminds of the good ol' days. That's what I think it is for me.
