Unbelievable. For me, the best combat system in any game ever made, with some of the cleanest parry windows and most brilliant boss fights in any game I've ever played. Sekiro is punishing and brutal until the switch suddenly flicks and you're bossing people for fun, and now your enemies are having a brutal time of it as you parry and Mikiri counter through its waves of enemies. A great game for musically minded people who can keep in time with rhythms, this is quite possibly the best "hard" game there is.
