At fourth grade we where starting our english classes at school, and my teacher asked - "What kind of words of phrases do you know in English?"
While the other kids in the class would say 'Cat', 'Dog', 'Horse' I would go for 'Nuclear War'. I didn't know what it meant, but our teacher quickly moved on with the lecture.
This is a fun strategy game. The more you know about world politics in the cold war era, more fun it becomes. This is why I used to come back to this game several times growing up, keep discovering new references to world leaders.
It is however not sustainable. The strategy is somewhat tricky and based very much on luck. Winning isn't rewarding enough, even though gameplay is fun. Once a short game is over, there isn't much insentive to play again.
