yeah but he was also a real guy, William Adams. British guy who got to Japan in the 17th century, was one of only two survivors of a ship from Europe. He got appointed as an advisor type samurai to the shogun for ten years because the shogunate wanted western style boats.

Also Nioh has you fighting wizards and giant frog monsters and stuff. It's awesome but I never once heard gamer types complain about historical inaccuracy.
