Before Cortes arrived in Mexico City, the Aztecs used to play tlatchli, a sport where the loser was sacrificed to the Gods. Today, Mexico City is home to a new wave of warriors that play in a modern-day temple - the Aztec Stadium, the world's largest football-specific stadium and the only one to have hosted two World Cup finals. Mexico City's massive population is divided into three groups: the azulcremas of Club América, the cementeros of Cruz Azul, and the felinos of UNAM.
