With careful reading and some thoughtful equipment choices you can become invincible in just a short period of time. It is a game of systems that has the complexity of a CRPG and the visceral combat of Dark Souls but with much more speed, finesse, and variety. You could easily complete Nioh in 30-40 hours and still get a lot out of the game, but if you dig into everything the game has to offer you might be closer to 200 hours once you’ve seen and done everything.
The quality of the game has increased steadily since release and they’d honed the systems and improved quality of life for players well before integrating PvP, three DLC releases, and several new modes. Nioh isn’t my favorite game of 2017 because of it’s lengthy main story or incredibly nuanced and fluid third person combat, what has kept me going back and playing this game the entire year is the amazing support that Team Ninja has offered for it.
