I keep observing that accessibility features often contain the tools we need to make our devices and apps more humane. This is one area that video games have been way ahead on.
There's a lot of movement in games over the past 5-10 years, so there's a lot more visibility into a11y there, but in general that industry still has catching up to do. What you are seeing is higher interest and velocity there, and given some time they'll definitely catch up with the slower iteration cycles in mobile and web a11y, but I guarantee you the story is much richer on the web (in particular) than it is in games.
