User blog comment:Bovell/Black Ops becomes top selling U.S. video game of all time/@comment-32136229-20110316065810

I've played all the seven main COD games and have been a Call of Duty player for over 2 1/4 years (yes, I play on the PC). So, this is my rank of all the main COD games from top to bottom:

1. Call of Duty 4: Modern Warfare 2. Call of Duty 2 3. Call of Duty 4. Call of Duty: Modern Warfare 2 5. Call of Duty: Black Ops 6. Call of Duty: World at War 7. Call of Duty 3 (I played this game on my PS2)

This is all based on my opinion. So, please don't flame me.
