A little late on this, but anyway, I think people overestimate how hard the first games were, doesn’t mean they’re not challenging, but people forget that they played these games in order.
I have my own story to prove how DS1 could’ve also been “The Hardest” for me too, how I spent either 8 hours or more beating the Bell Gargoyles with a Halberd, on some level 24 character as I remember, without any weapon upgrades, or any resin. That doesn’t mean they’re the hardest boss, or DS1 is the hardest, it means I was still learning and through them I got good enough to beat O&S solo much faster in that playthrough, fast rolling with my trusty Zweihander.
for me right now, the hardest is the one giving me more trouble with all DLCs and optional content counted, 1, BB, 2. DS3 3, DS1 / DeS / DS2. I look at them from how difficult they were also on replaying them, except for DS2.
