I am noticing a pattern of liking the songs that are more based on games I've played. For instance, I love anything you've made about Skyrim, Batman, or Mass Effect. I even enjoyed Fire in Your Hole, though I've never played Bulletstorm nor have any interest in doing so. But I did play the demo and watch all the trailers and footage before making that decision, so I at least got the game. But this? Never played Dark Souls, never seen any trailers, no interest in it whatsoever. Once you start signing, I found it hilarious, especially the opening lyrics, but the rest, eh. Not my favorite.
Ah well. My loss.
EDIT: Actually, what this reminds me of most is Warhammer, with the over-the-top tone.
