well, thats good, that means you wont wanna play the campaign of a good war game . . . I finished COD4 solo campaign , verfy good , same thing for this one , never said i will not play the solo
a game that shows what war can be like and just how messed up the world we live in can be, play the multiplayer
Just go on Youtube or other :Look at real bad scenes or a document where you saw an army car returning to base with one of the guy killed : just lot of blood when they opened the back door ! And the team not crying but would want.
'that's reality not video game here)
Already seen emotionnal situations bad things :
- A guy cutted in two parts ( legs flying ) , cutted by a car going too fast : legs lying on road near my parents previous home.
-In parachute in army i was, two guys dead in a simple parachute exercice
-I've been attacked by crazy people !
. . . I stop here

I don't really need to experience bad situations, and i already know at some point how war is horrible for soldiers and civilians.
But don't forget :
Vietnam and Second war were even lot lot more horrible than today wars showed in Modern Warfare.There were big camps where millions of civilians people was transported by train before been burned.
And the number of soldiers that where shoot in Vietnam.
And you just find fun FPS games to play, in that periods of war.
Perhaps show you the horror of civilians killed in second war in a game , juts would make you more motivated to really kill bad ennemies finally.
In GTA4, already allow you to shoot civilians !
and you play the entire game as a bad ass killing people.MW2 feels more realistic caus it's turned like a real documentary war where you play through war events narrated (simulated) like real ones.
Another realistic point is the dialog sound :Without it , no immersion, Metal Gear Solid 1 , even with simple graphics, the dialogs brought characters to life indeed.
(i played a game long time ago and just remember i was really scared by screams) :
I can't imagine a game with a scene, where you would have very real loud screams of panic from a civilian :
(not Doom 3 standard screams that really sound played !)
Very well done screams by a really talented professionnal people , like it could be in real life , you would be very shocked also !
But perhaps good if that game can show to some young people that war is horrible.
Personnaly, i don't need it, i already know it at some point!
