Then why can't they make their games like every other game and include difficulty settings? Those who want the challenge can go for it. Seems like it would appease everyone.
It's frustrating because Elden Ring did so many things right that other open world games get wrong.
FromSoft games do have difficulty settings. It's just that they're baked into the gameplay and not something you select in a menu.
Want a hard experience in one of these games? Roll a strength build. Don't summon anybody to help with bosses. Don't use spells. Don't use spirit ashes (Elden Ring only).
Want a much easier experience? Go with a mage. Melt bosses at range where they can't touch you. Start every encounter with Mimic Tear or Black Knife Tiche. Summon coop partners for bosses.
Admittedly, this is sometimes hidden from the player. Most people who play Bloodborne can go through the entire game without realizing that it's even
possible to do a spell-caster, and they'll probably need to follow a guide to figure out how to do it. But spell-casters in that game just trivialize every boss encounter except Ebrietas and Abhorrent Beast, both of which are optional.
