are you aware of the meaning of the word “setting” in this context?
Just in case I can explain:
It means you can switch something from one behaviour or effect to another, basically giving you a choice of how something should work.
So, adding a difficulty setting changes nothing about your experience of the game.
do you need more words to explain this simple thing?
I can try to use simple language and shorter sentences if you require it?
all of the things you say are completely, 100%, unaffected by a difficulty setting.
The only thing a difficulty setting changes is that some people can say “I am better than you, I beat [game X] and you didn’t”
that’s it.
and even that is a complete illusion, see the prominent worst business man in the world, paying someone to make PoE ranks for him. Also there are mods, cheats and plain lying.
This whole thing is excluding people, and for what? Literally worthless bragging rights.
