I like the snare.
Whenever I heard this song in the game I always felt like I was being put in front of a firing squad, and this brought that memory back.
It never occured to me before, but hearing this theme without the layers upon layers of synth that usually gets appied to it makes me realize it's darkly similar to the SeeD Theme from FFVIII. It shares some chordes with it at least, and that's creepy considering how different they are.
