No they are two diffrent games.
It not a part of Call of Duty Modern Warfare 2
Yes i can : )
Unfortunately no, you can't play multiplayer on Call of Duty Modern Warfare 1 or on Call of Duty Modern Warfare 2 on the same screen. But on Call of Duty Modern Warfare 3 and Call of Duty Modern Warfare Black Ops you can play multiplayer on the same screen. There is an new Call of Duty Black Ops 2 coming out soon though, so I expect that to also have that feature, since its newer.
Yes i can : )
No you cannot
No because the game for Nintendo Wii is not Modern warfare 1 it is Call of Duty Modern Warfare Reflex Edition and It is not a Call of Duty 4 Modern Warfare or a Call of Duty Modern Warfare 2 and that is why the name of the game is different. You should still be able to use any regular controller that is approved for the Nintendo Wii
Modern Warfare 2 is a better game if you are going to play online.
I'd go more to Call of duty Modern Warfare 2 :) As for world at war it has a bit less graphics and game play as the other does. The game does not exist for Nintendo Wii. The Only Modern Warfare game for Nintendo Wii is Call of Duty Modern Warfare Reflex Edition. It is not a Call of Duty 4 Modern Warfare or a Call of Duty Modern Warfare 2 game and was not even designed by Infinity Ward , but designed by Treyarch and released in November 2009.
Yes.
No it doesn't.
yes you can
