I have done my duty!

After completing Black Ops, Modern Warfare 2 and World at War in the Age of Modern Warfare 3, here I was playing Modern Warfare: I series backwards. What to say? It is excellent as many other games. I understand why he was proclaimed best FPS of all time, in his time. This is a Call of Duty, and then that's it, everything is said. Speaking of duty is to believe that it was me who made me play all the CoD.
