It's not that I hadn't S-Ranked a game before, but they had always been on PC, on either GFWL or Steam. Dead Rising: Case Zero is my first console S-Rank, and I'm damn proud of it. I finally feel like I'm playing in the "next gen"... which would be "current gen", I guess :P 
 
What about you, GiantBomb? Which was your first S-Rank ever?
