There is no difference just two different games
Call of Duty 4 Modern Warfare was developed by Infinity Ward and takes place in the Modern World. Call of Duty World at War was developed by Treyarch and takes place during World War II and is based on several historical battles
Modern Warfare is a year older
Modern Warfare 2 no doubt about it.....i acctully have both and the graphics of world at war just suck compared to modern warfare 2
Modern Warfare 3 IS World War 3.
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
No there are World at War then Modern Warfare 2 then Black Ops and on November 8 2011 Modern Warfare 3
Call of Duty World at War, Modern Warfare, Modern Warfare 2, Black Ops, and Modern Warfare 3 all have online multiplayer.
No. CoD World and War and CoD Modern Warfare are though.
World at war was the next release, but you could also get Black Ops or Modern Warfare 2 and on November 8 2011 Modern Warfare 3
Modern warfare the best, unless you want ZOMBIE NAZIS in which case go with WaW.
yes
it will be the best game in the world
