DS1 > Sekiro > DS3 > Bloodborne > DeS > DS2
Finished the game yesterday and jumped back in to NG+ right away. First playthrough was about 40 hours. Made it through all but the last area in NG+ in about 6 hours, mostly due to the fact that I've only died a few times. Sekiro is way more mechanically demanding than any of From's previous games, but is also a lot more rewarding when you are executing perfectly. It's felt incredible to tear through all the regular enemies and most of the bosses on NG+ solely on the virtue of having really locked in the parry mechanic.
Dark Souls 1 still does it for me more in terms of environment, level design, and enemy design, but holy shit Sekiro might be the most raw fun I've ever had with a 3rd-person action game. Now just give me a Star Wars lightsaber combat game with this style of parry/deathblow focused combat.
