By popular (or in this case critisism) i will revise this OP
Here i want to list some possible inspirations in Mw2 maps
it is more evident in mw2 (because that was the last game the old/good infinity ward made)
the following is comparisons of possible inspirations from cs to cod
mp_Terminal = cs_747?
the most obvious part is the airplane’s very presence; but also how the enterence of the airplane is on the left side of the plane (when looking at the back)
there is also a back ladder to enter the 747 from the rear
the repective airports also have a prominent window scene in front of the plane http//www.themodernwarfare2.com/images/mw2/maps/terminal-prev.jpg[/img]"]
mp_karachi = de_karachi
actually this one is actually a fact since the original map maker works at old infinity ward and remade his own work for mw2 (though the mw2 version is much more balanced than the 1.6/source map)

mp_highrise = de_vertigo
Highrise at one point in development was named “vertigo” and the latter was also set on a skyscraper. Although in mw2 there is a mix of construction and offices
favela areas = de_rio (custom map)
both maps are set in brazil, but most of all, they both have a small soccer field within the playable area
updates to this post will happen (when i get back to it lol)
but now is the chitchat time
