With respect, I don't see how CMSF, which will be about a current day US invasion of Syria, will be less controversial or more popular than a WW2 game and yet BFC has decided to tackle that subject. It will inevitably be compared to the US invasion of Iraq in 2003 and the continuing civil war.
I am planning to buy CMSF, not because I love the subject matter, but because I know BFC will do a good job, but I would also line up to buy a CM game based on WW2, the Korean War, the Vietnam War, the june 1967 or october 1973 War or even a IDF module to CMSF for the same reason.
