Nioh is a game like Dark Souls, but in Japan. This is a fun game. Most of the game is VERY RPG heavy, like status effects galore, a large range of weapons, the same weapons with better effects and damage numbers, higher levels, etc. If you can understand that stuff well, then you got this game. The bosses are super unforgiving, but most of them have exploitable weaknesses, like the oil guy is weak to fire, and how the vampire has really good tells. The problem with the bosses, though, are that they are ridiculously unbalanced. One of the early bosses will destroy you. I hate you vampire. The levels are pretty linear, but exploration results in better weapons to smash the bosses with. Overall, pretty fun game, just super complicated. 3 yokai out of 5.
Combat is similar to Dark Souls, but with a living weapon and more complicated stamina, skills, and health values.
