Summit is a Cold War board wargame introduced in 1961 by Milton Bradley as "The Top Level Game of Global Strategy", with an updated release in 1971.
Each of the six playable "countries" are different bright colors while unplayable regions are various shades of brown depending on their economic and military "value".
One of the primary strategies of the game is to threaten an invasion by deploying one's military and economic power cards unless an opposing player dismantles their bases in one of the brown regions.
This scenario came true one year after the game was released in the Cuban Missile Crisis of 1962 when U.S. President John F. Kennedy demanded that the Soviet Union dismantle its bases in Cuba and the world came close to the brink of nuclear war.
