Team Ninja, creators of Ninja Gaiden, decided to put proven principles to good use. After a long development process (work on the game started as far back as 2004), they created their own take on the action-RPG: Nioh.
In Nioh, the player takes the role of Irish sailor William, who flees from his native England to the mystical land of Zipangu (Japan) to escape imprisonment. Upon reaching his destination, he gets mixed up in the conflict between Japanese warlords who war over control of Japan. The characters and setting are based upon real history, with many familiar names and events making an appearance, all of it mixed with a healthy dose of fantasy and Japanese mythology.
