Supreme Command

A fairly good World War II simulation set in the European Theater. The game is exceedingly rare.

Old-Games.Ru describes it as:
Supreme Command positions itself as an “educational game”, and this implies a certain special presentation of “educational” material and, in fact, its presence. In this case, it was meant that this game will enlighten you in the field of the chronology of the events of the opening of the Second Front by the Allies. But! No dates of key battles, no information about training and balance of power, no list of politicians and generals, etc. - none of the above is in Supreme Command . Only a vicious agitation meets an unlucky player as an introductory word.
