Im pretty sure Mw2 is better because i have both and mw2 has a better multiplayer.
Mw2- 9 out of 10
Cod4- 8.5 out of 10
cod 6 mw2 cod5 cod4
All of them I have COD3 COD4 WAW MW2 & BO for the PS3 I mean out of WaW or MW series I have BO and MW2
for black ops they Will give you 20 dollars and for cod 4 10 dollars
CoD MW2,CoD4,CoD world at war and CoD black ops (when it comes out of course)
I think MW2 is ten times better.
COD MW2 is a much better game than WAW because the guns on MW2 are much better and more powerful. Trust me i know what im saying is true!
there is no g3 in the game there is one in COD4 not MW2
Cod mw2 has better graphics so cod is he'll better
CoD MW2 Because L4D2 is WAY too repetitive and you may get bored fast While CoD is Action packed and Great online. Spec Ops is another great thing in MW2.
man ... in cod4, infinity ward didn't focus on offline multiplayer so you cant level up but in cod mw2 this problem is over ... GHOST out . (overlord mw2) EDIT BY SOMEONE ELSE: The only way you can is to hack or mod, I dont know how so get black ops when its out or get MW2
cod mw2 is better for xbox360 because you just push bottons not like on PC you have to move the mouse and do lots of things.but if you are use to the letters of your PC you could buy it for PC.
basically mw2 but for wii, since they didn't make mw2 for wii
