Friend of mine tried Bloodborne for the first time and beat Cleric Beast on the first try, at whatever the default level is. Only other From game he played is Elden Ring, which he played for like 150 hours, so that's probably why. He was like "I thought Bloodborne was supposed to be super hard". He did have a rough time with the first boss, at least. Cleric Beast almost killed him a couple times. Then he just stuck to the foot and circled around it constantly. Was a "you sure you haven't played this already?" situation.
Demon Souls "half HP" penalty for dying sucks. Having to devote one of your two ring slots to the Cling Ring for the whole game sucks. The worlds getting harder if you cure the death penalty REALLY SUCKS. That world tendency thing is so obnoxious and I wish they would have tuned that in the remake. It's the main thing that makes Demon Souls hard to recommend to people. Which is unfortunate, because otherwise, it's a pretty easy game (compared to the others) and could have been a great entry point for someone that wants to get into other Fromsoft games after Elden Ring.
This is pretty much it yeah. Dark Souls 1's world design reminds me of Super Metroid or Metroid Prime. It's one of those extreme few games to feel like am actual place in a world. Then Dark Souls 2 just has a bunch of wildly-different levels stuck together and traversed via warping between them.
