Query: Best CoD game yet!

I got this game for Christmas, and ended up beating the single player campaign on the normal difficulty setting the same day. Short? Absolutely, but crank it up to the "Veteran" difficulty and it should last you awhile (heck, I haven't even beat CoD 2 yet on Veteran). I can't really comment on the online portion of this game as I am currently switching ISPs and am waiting for the installation guys to come over (curse you, Verizon, and your lack of installers), but from what I can tell that is where the game really shines. I highly recommend this game for fans of previous CoD titles and Battlefield 2 players alike. After the last Call of Duty I was beginning to worry about the series, but with Infinity Ward back at the helm the game has returned to greatness.Welcome back, Infinity Ward. You were sorely missed.
