I actually mentioned that game but no one bothered to say that was so different. I think they just want to ignore it.
EDIT:
Again, where are you getting that information? The game is a work of fiction. Also, are you against the "Black Hawk Down" games? If not, why? They are much more of a "realistic portrayal of events which actually happened in a real-world setting" than Modern Warfare 2.
You play as an attacking force that can slaughter civilians... But wait, because the attackers happen to be Delta Force members that doesn't count! the US of A is always right and can kill anyone without being evil! That must be true!
