I personally like the eras preceeding the WW era, especially preceeding the Genro, and their military agendas. The days of the Bakufu and their reign during the shogunate of the Tokugawa clan, I think were some of Japans greatest years. The Bakufu refined all of the Martial Arts of Japan, especially regarding the daimyo and their use of the samurai as a means of acquiring more land holdings. THe shogun was wise in consolidating the ninjas under his authority and placing them under his command.
