You actually have these mixed up. COD 4 was the first "modern warfare" game, and Modern Warfare 3 is the latest one. I would reccomend just going for the newest one, but I guess you may want to try the older one first for some reason.
DON'T! Modern Warfare 3 is a HORRIBLE game, its unbalanced. Example: The damn hit detection is utter ****!
, you can knife people from 5 feet away, and the spawn system is BALLS. Call of Duty 4 is a MUCH better game.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
