That exact video is what I had in mind when I made that point.
David Lynch, Taratino, Speilberg, Scorcese, Soderbergh and even Alfred Hitchcock worked in TV. Clearly, at one point or another, they acknowledged that conveying good content through the medium of film is secondary to the format it is presented in.
It's why I object to people placing so much emphasis on the format of Dark Souls. If people don't play it how one person envisions it (even though it was actually made by multiple creative professionals, all with likely differing perspectives), then it isn't substantial. The notion is staggeringly reductive. The game is a multi-million dollar project, funded and overseen by multiple committees of people. It isn't some solo art-house piece attempting to desperately defy industry conventions, though some folks on this forum behave like it is.
So when actual and perspective members of your audience come to you, asking politely to consider people with different needs, it isn't even remotely unreasonable. In the end, you are providing a product that people are paying for, specifically one that requires their agency to see through. I wouldn't expect to make a product and not receive feedback. Whether you have to act on that feedback is a different story. In the case of Dark Souls, I see it as wasted potential. Namco and From Software's leadership might not feel that way, but I will keep on pushing my views in good conscious.
Also, I saw some folks insisting that disabled people were being
used as a moral strong-arm. That is a disgusting counterclaim to people who have a legitimate interest in empowering folks who demonstrably cannot participate in certain experiences because of physical or mental deficiencies. As someone with sporadically crippling panic and emotional fits, I have nothing but sympathy for people with problems much more serious than my own. It's fortunate that I exist in a minority of high-functioning people with mental illness, but not everyone has the same needs, nor do they often ever have them fulfilled.
I also never pretend to know better, just because of my own anecdotal experiences.
There was a fair point that we should differentiate between accessibility and difficulty, though I think examples like Dishonored 2's configurable difficulty is an instance where both can overlap.
