In Tianxia, players take the role of leaders of noble families who want to earn prestige, as well as favors from the powerful rulers that govern the seven Warring Kingdoms. The game lasts four rounds, in which you install Governors in the regions, bolster the power of rival ruling houses and thus their favor. You also sell goods to merchant ships that sail the Chinese shores to gain wealth and various other benefits. Nevertheless, you must not forget about the nomadic warriors who pose a constant threat on the northern borders of the seven kingdoms. Thus, you must train soldiers and build walls and towers to weaken the invaders and protect your interests, earning prestige in the process. Each round the Nomads (Xiongnu) advance toward the borders of the seven kingdoms and gather even larger numbers. When they reach the border, a battle takes place that affects all players. At the end of the game, the player who was the best governor, politician, merchant, and protector becomes the winner
