Different game genres have different customers.
Don’t play souls like games… I don’t play certain genres of games because I don’t like them.
Personally, I love challenging games that I have to think deeply how to win. I have adhd and I like to play games that make me think and require strategy. My disability allows me to play these games better.
What you are saying is the equivalent of “horror games shouldn’t be scary”. That’s to the core of their game genre…
I would agree that games could improve their accessibility modes.
Everyone is different, let people play the games they like.
