When I was in Afghanistan, and most other Arab countries, there was trash everywhere. I mean...everywhere. Your maps are as clean as a whistle. I think it would add to the ambiance quite a bit if you added litter pretty much in every crevice and crack. Plastic bottles, rags, tarps, filth, dead animals. Lots of dead goats. I think that would add to the realism substantially. Also, fires. Anywhere there is war there are fires. Burning tires, houses, vehicles. It would make everything less sterile and more like a warzone. In addition to that, you should see about buzzing noises. Flies and mosquitoes are everywhere over there.
Thanks for your hard work. I'm very impressed with this game!
