Missile Command is planning for a real missile defense system.
Chess is obviously based on war. Your claim is that it is based on killing the enemies king, not that it was simply based on war. Showing a video game that is intended to be based on a missile defense system as it is called "Missile Defense" isn't some grand idea. Chess isn't named "kill the enemies king".
Kings usually lead the armies in battle, like in the movie Alexander.
That is what "checkmate" literally means: kill the shah, kill the king.
Wrong again, shāh māt means "the king is helpless". It also isn't the oldest name for chess as we understand it. The oldest name is Chaturanga which has nothing to do with the king. The term "shāh māt" comes from ancient Persia where the idea of announcing check and the rule that the king cannot walk into check nor be left in check was created so bringing it up is not in your favor at all.
