Black Ops has not only met my expectations, it's surpassed them like a motherfucker. Best single player thus far. Best multiplayer thus far. Easy.
I was blown away by how much Treyarch have grown as storytellers. As someone who is into the game mainly for the campaign (insane, I know) I was not disappointed. If you're like I was and are a little sketched out because of WaW, it's all good. Be at ease my friend.
If running around dusting fools as Ed Harris can't convince you of this games awesomeness, you can get the fuck out.
