Regular dogs/wolves/monkeys die in a single hit of a shuriken btw, they're far less of a threat than they used to be in groups in older souls.
The game gets creative with regular enemies at the last area of the game, but that's about it. It's the only area where using stealth is actually not a waste of time (in the early game it's more larp than real use) because of a certain ranged mechanic enemies have.
Otherwise if you're doing stealth on anything except minibosses, you're just larping because you could just run up to them, kill one, jump like a monkey and hit another etc.
Or run far enough and lose aggro, then run back and backstab. Enemies don't notice you fast enough when you run to their back, meaning you don't need to crouch stealth to backstab kill one of them.
I wouldn't say the boss variety is like any souls game either. The content reuse is stronger than other people here are willing to admit, to an extent that's really damning. Area variety suffers the same issue and the storyline makes you retread ashina not once but twice (removes your
bonfire idols access and make you get back to them). All souls game had content reuse but the amount in Sekiro is extremely damning. I'm now 33 hours in, completed most content despite myself (skipped all the headless shit and demon of hatred), haven't killed the end boss yet but mastered the first two phases to the point of doing them no-hit no-heal and I felt like there was about only 15 hours of real content, with the rest being padding to dramatically lengthen it.
And that's exactly what's wrong with the game right there. So much shit is repeated. You die often to a phase of a boss but have to retread the same previously mastered moves ad nauseam. What I found bearable because it was just one spectacle boss in Friede in DS3 is now a standard fare and many enemies will be met multiple times.
It's a bittersweet game because there's a decent amount of positive about the combat. I don't dislike learning the final boss and I didn't dislike many other bosses. But the tedium of phases and length of fights gets to you.
second encounter takes like 10 minutes. That sort of thing was already testing my patience really hard in Dark Souls 3's DLC ( Gael and Midir )
If the next From game is anything like this it'll be no-buy for me.
