There’s been a bigger push in the last three or five years to make games more accessible. I mean, if you think about it, just 10 or 12 years ago most games didn’t even have subtitles or colorblind modes. Now they’re making games specifically to be played with one hand, text adventures are being fully voiced, VR games being visual experienes that don’t require hand-based inputs, etc. It’s not the most rapidly progressing area, and has obvious difficulties, but it’s something.
Your remark that it’s about money is cynical. I admittedly didn’t watch the entire video, but in the few minutes I did I didn’t see anything but people genuinely trying to make games accessible to those with physical limitations. Even if it was driven by greed (it is an increase in potential audience, after all), it’s an effort to bring gaming to those that can’t experience it as things are now.
My brother only has one functional hand and I know that he’s always loved video games but struggled to be proficient at anything that requires both hands (95% of games). I don’t know what it’s like to live with such a limitation, but I know that if my life didn’t have video games in it, I’d lose my damn mind.
EDIT: I feel we’ve gotten off topic.
