Ooooh, Crisis Core. Good lord I love that game. I'm level 60 and currently in a constant stalemate battle with the '1000 ShinRa Infantrymen' mission. I have a mastered Quake, though, and that certainly helps once I hit a 444 on the DMW.
I'm pretty sure my sewing machine hates me for playing that game, though. It really disagrees with the vinyl I'm using to make my SOLDIER armor and belt.
