I have both!! I play CSS when i want to shoot people in the head and WOW when i feel like stealthing up on warlocks with my rogue and owning them. WOW is so addictive. If i could i would play non stop!
WoW consumes the soul, digests your mind, and shits out your remains. It was by far the most pathetic year and a half or so of my life. I'm so glad that SpN and Bomb and I gained some sense. "Fuck you Blizzard, hello Geometry Wars"
