I'm nearly finished with Sekiro. I've enjoyed it so much that I've redownloaded DS1 and I'm going to finish it this time, even though every one says that the second half starts to suck.
I also dropped Nioh 1 a few year ago because of an annoying fight. I've heard mostly positive things about Nioh 2, so I'll probably buy that if I still have passion left for this genre after I marathon the other games. I might look into emulating the original Demon's souls too.
God, I'm going to miss Sekiro. It made me care again.
