Okay, so the premise is simple. In late 1979 a conventional war breaks out between the East and West. Fighting on every continent which will last for over a decade. Other conflicts will flare up too. I'll not go into major detail until I get some interest, but for now I'll put up a brief summary of the factions and a CS.
