Personal opinion. Cod4: Modern Warfare maps are better and the game is more colorful.
Call of Duty: Modern Warfare: Reflex
Modern Warfare 2 all the way dude. But just wait for Call of Duty: Modern Warfare 3 coming November 2011
Modern Warfare 2 is a better game if you are going to play online.
call of duty world at war
Modern Warfare is rated a little higher than World at War see related links for both games
A matter of opinion.
Call of Duty 4: Modern Warfare was just before Call of Duty: World At War, and Modern Warfare 2 came just after it. Unless its on the Wii, on the Wii its WaW the Modern Warfare but its called Modern Warfare Reflex
