When it was first released, the Genghis Khan titles were highly successful in Japan. The first title was an instant best seller since the game offered a similar yet different system than the Nobunaga's Ambition or Romance of the Three Kingdoms series. During the series's run, it was unofficially dubbed as one of the big three historical simulation series in the market. However, sales for the fourth title were significantly lower than the other two series. This is a likely contributor for discontinuing further entries.
