SAC---All out Thermo-nuclear War against the Soviet Union: 1962
The game is very basic and can be played in probably 10-20 mins at most. I was thinking of adding more detail to it myself to give it a more realistic feel (the Russian interceptors, for instance, all function the same even though they represent different kinds of aircraft. Assigning different ratings to them could make things more interesting.)
