KCD2 easily. I got about 90 hours into my playthrough before they finally patched in Hardcore mode and I started over. The base game balance was pretty poor by mid game, I was just stomping everything, making lots of money etc. I still had a lot of quests in the Kuttenburg region and it just felt like I would rather experience that the best way, which is hardcore. Not just for the increased combat challenge, but because navigation and exploration are much more involved when the player position is no longer shown on the map.
I'm taking a break to play Death Stranding 2 which will also probably end up being 80+ hours.
