Nioh is definitely a must play, I am a dark souls veteran, played through 1,2,3 and bloodborne all the way to ng+. But regardless of my experience Nioh 1 really destroyed me with basic enemies, forcing me to adept to its controls, changing my combat style from safe to aggressive. Nioh 1 and 2 gave a me a fun and engaging challenge that I have long desired and it truly is worth your time.
Note: if you are a first time player I recommend doing a duel sword build as it’s pretty fast and gives you some basic easy to learn combos that do a lot of ki damage.
