Pretty neat that you were able to get it early, but too bad you don't have the console to play it yet, haha. I have it on my Xbox 360 and I'm not impressed at all. It's a very bland and boring rehash of Modern Warfare 3. Probably just going to sell it the next time I decide to head to Gamestop. As for Kosh, I have to entirely disagree with what you said about the Single Player and Multiplayer. The Single Player is a short, rehashed joke. Terrible voice acting, boring set pieces, and the "Riley" missions are so horribly boring. As for the Multiplayer, it feels EXACTLY like Modern Warfare 3. At least Black Ops 2 felt different, but that's not the case here.
Maybe some of the prettier graphics (Which won't be that much prettier) will distract you from the mediocre game play. Also, we're promised, but still have yet to receive the magical dedicated servers that the Next-Gen consoles are supposed to be able to handle.
