This game absolutely allowed me to live out my fantasy of being a samurai in feudal Japan.
The combat was punishing but fair, and like many games is hardest at the beginning when you have so little health and resolve that you'll die in a few hits if you don't learn to master the skills of parrying, dodging, or breaking an opponent's stance. The more skills, weapons, armour, and resolve you acquire, the more forgiving the game becomes.
There are so many playstyles on offer that I never really got sick of any of them. I rotated through so many options; playing as an archer who was always in slow motion as long as I kept getting headshots, being a stealthy ninja who assassinated isolated foes with a quick stab to the neck, being an honourable warrior by having stand-offs and killing foes in honest one-on-one combat, breaking foes defences and keeping them constantly staggered, raining extra-strong knives and bombs down on my opponents, or just being a freaking bulwark and getting stronger every time someone hit me. The only playstyle I never really explored was the "terror" build, where certain actions could cause your opponent to fall to the ground in panic. These were all equally viable, and just depended on what seemed most fun to you though.
One of my favourite parts of any game is cosmetic changes. Fighting on behalf of a samurai family? Better don their armour and wear their colours. Going on a stealth mission? Ghost-suit up. Enterring a snowy part of the map? Better equip the armour with the fur cape and a facewrap. I switched outfits thousands of times throughout the game, and I wish there'd been a quick-load button for it, but I got pretty used to changing my hat, mask, sword etc. to create different styles for every occasion.
Special mention to the Fundoshi armour, which you only get at the end of the game once you've visited every hotspring - I thoroughly enjoyed running around Japan killing bears and slaughtering mongols in that particular outfit.
I'm not normally a fan of sandbox games because I tend to get overwhelmed by seeing how many markers are on the map, so I really appreciated the "fog of war" that kept most of that information concealed from me. It was a pleasure to gradually uncover new missions, strongholds, and secrets: I especially loved the secret shrines, and the voicelines/reactions that came when Jin bowed in different circumstances.
Also special shoutout to queer inclusion and the lack of judgement around polyamory. That shit never gets old.
All in all, I spent ~60 hours playing this and came very close to 100%'ing it, but I felt like I'd derived as much satisfaction as I needed to. Maybe one day I'll play New Game Plus, but until then, a very well deserved 9/10 from me.
