In all honesty, the multiplayer component is so well thought-out that it could have been released as a stand-alone experience. The campaign is roughly a six to seven hour ride, and a great one at that, and the multiplayer has a shelf life that will likely outlast the console it's played on. This game is jam-packed with content that is very well worth the sixty-dollar price tag they're selling it for.
Their new vision for the Call of Duty series is definitely a bold step, but it's a step in the right direction. But aside from those minute missteps, Treyarch did an amazing of proving they can innovate within this franchise, and not be held back by their publisher's ongoing dispute.
