cold war isn't modern, and wasn't really a war at all (we kept getting closer and closer to war but it never actually happened.
think about how bland an iraq based game would be:
-9876700357909 identical maps (sand and poor shacks galore)
-gray as far as the eye can see
-having to call in to ask permission to return fire (lol)
-M4/M16/Barret would be the only US weapons
-Ak's and improvised explosives would for the most part have to be the only iraqi weapons.
the game has to be one of the last two, or something different.
