The game looks awesome...but I don't agree with the title. It just doesn't seem right calling what is traditionally a World War II game "Modern Warfare." Modern Warfare doesn't instill a "call of duty" like the Second World War did. Even the “War on Terror” post 9/11 didn't instill such a call. It may have inspired a “Call of Patriotism,” but not a “call of duty”.
That's just my opinion. Having actually answered the call to serve my country, I hope it counts for something.
