Sekiro is its own genre. The only "souls" like thing is the difficulty. Sekiro has the best combat system in the history of gaming. It forces you to deflect (parry) attacks from small lizards to literal Dragons, has incredible stealth mechanics, and a combination of arts and items to use. People just want to dodge and kite an NPC, while Sekiro forces you to fight, but 1 vs 1, the game doesn't encourage you to hack and slash through enemies. I've been playing the game since 2020 up until 2022 "file shared", then I bought it on Steam and replayed it with all achievements gathered. It's one of the best games in the history of gaming, and I hope Fromsoftware uses the mechanics from Sekiro for a new game in the future. It's also the only Fromsoftware game to be properly ported on PC because the publisher is Activision and not have those console controls when you start up on PC.
