5 out of 7 enemy civs (medium difficulty) decided to play a game of "forget over the human." All of them sent goddamn loving hordes of rock throwers and clubmen at my village which had NO MILITARY and NO TOWERS. When the fight started, my citizens were like roosterroaches exposed to the light suddenly. When I finally rallied them (and the enemy destroyed half the village) I pelted them with spears until a few stragglers were left, which promptly killed each other. They did this over and over through the first epoch all the way to the dark ages, then I finally saved and quit the game.
