Let me take this time to explain the progression of the "COD" franchise from the beginning all the way to the newest one thats not out for awhile. Maybe this way, people will stop inventing games. Ex) Call of Duty 5: Modern Warfare 2. "This will not take into account the deviations like Big Red One and Finest Hour."
1) Call of Duty 2) Call of Duty 2 3) Call of Duty 3 4) Call of Duty 4: Modern Warfare 5) Call of Duty: World at War 6) Call of Duty: Modern Warfare 2
seriously why can't we call wold at war cod 5, your so called modern warfare 2, which probobly will either have its name changed or be changed completly like every other game usualy is asumining your sources are reliable, doesnt have a number 5 in it so why should that be called number five?
