I'm toying with a campaign idea that pits the evil European Federation against the rest of the world, who will just be trying to defend their homelands. After unifying Europe, the European president now wants to bring the rest of the world under the one umbrella, believing that by conquering everyone he will put a stop to military conflict for once and for all. Of course, the human life that is lost in this conflict will be worth it in the long run so that future generations do not have to live under the threat of war.
I also want to try and avoid games set in the middle east, as I reckon that is going to be overdone. I'm thinking about games that put the MEA or PLA into a position where they are invading Europe or US, so instead of dusty middle eastern buildings there'll be a high street with a bombed-out McDonalds
