Another game has a way of including civilian, military, etc, NPCs into the game, as well as a setting to prevent it from being activated by players unless they're in the zone where it activates. I mean the game is old, and it doesn't affect FPS too much, it still puts a load, hence them activating unless you get a certain distance from the zone. So no, as people have said, DCS is a bit on the CPU as it is, and could you imagine all those cities (or just one) spawning a lot of civvies or troops? Not worth the effort. And as mentioned above, it's just not worth the CPU hit to render all those people. Great for immersion, yes, but not worth the pain it'll cause.
