If you haven’t played Ghost of Tsushima, I urge you to do so. It centres around Sakai Jin, the sole survivor of his clan. He is also one of the few surviving samurai following the Mongol invasion of the island. In his quest to save the island, he will have to set aside his ways as a warrior, and fight in unconventional ways.
As far as stories go, Ghost of Tsushima serves as a really good base to work with. The movie can easily drop quests for acquiring skills and armor for a more streamlined plot. And with Ctahelski behind the proverbial wheels, it’s probably safe to expect action as good as that found in John Wick, which are among the best in the business. And now that the game is known worldwide, the movie may be the chance for their creators to adopt a more historically accurate take on the iconic Japanese swords.
