Gotta be DS3. It was my first one and the game lets you treat it like a boss rush if you know it well, so I've got several NG+ cycles that were completed in a day each. It has less running around / travel time required than DS1 and 2.
Haven't played Bloodborne (thanks, SONY) or Sekiro (soon tho).
I want to try it, but I'm not extremely hyped, just somewhat excited. The fact that there is day one DLC is a bit of a bummer in the way it feels like a cash grab.
I'll definitely wait a bit to make sure From's famous netcode is ironed out first. Maybe wait to see if there is a sale during summer.
