I have also not beat it yet but was enjoying it more than Elden Ring (which I have also not finished).
I think Sekiro is still my personal favourite out of the games they've made. Dark Souls might edge it if I did a top 5 due to the nostalgia factor. Honorable mention to Bloodborne.
Wish From implemented multiple save slots, I want to go back and experience the story progression again without losing all of the weapons/gear on my original save file... Replaying missions just don't feel the same and I can't lend my device to a friend to let him progress on his own. PITA to manually replace the save file too because I'm playing on the Deck.
