Hi
I work in the games industry now but my background is in media and games studies. I wrote a long research paper on accessibility and dissabilities in video games and game design. I did a lot of research on the subject and I think it is important especially for game devs. Accessibility in game design can be easy and give you a bigger target audience as an estimated 20% of gamers have some kind of disability (by their own account) and most of the adult population will sustain a temporary disability before they retire. That means that a significant number of people might not be able to play your game and that usually go unnoticed.
I would love to share my research and tips in some articles if there is any interest in the community.
