9. Muramasa: The Demon Blade
Among the few "mature" titles to hit the Wii was 2009's Muramasa: The Demon Blade, an action RPG set in the Edo period of Japanese history. With bold 2D illustrations that drew inspiration from the era's mythology and traditional Ukiyo-e art style, the game was a treat for the eyes and well deserves at least a digital re-release on the Wii U's Virtual Console.
