Is singleplayer in MW2 and MW3 shorter than MW?
 

I just completed Call of Duty 4 Modern Warfare, and although very, very exciting, I found its single player campaign even shorter than United Offensive. Is it more short in the other games?

they are longer, MW 3 is longer tan MW 2 by about 4 missions. MW 2 is longer than MW by about 3 missions

I think mw is a bit longer than mw2. But mw2 has better missions. It was really interesting. I have completed mw in 6 hours 10 minutes. And it took me 5 hours 25 mins to complete mw2.
