Hi,
I think, since you asked, that what they are doing (or anyone that's making games more approachable to people with disabilities) is super important. Giving people the ability to escape, be it their physical, mental or social reality and enjoy soaring through some blue skies for a couple of hours may seem small, or even counter productive, but it has the ability to grant strength, strength to deal with some harsh reality that for most of the time is all you experience, it gives you the opportunity to take a step back and maybe re asses a situation, or just make some new friends and have a few moments of pure fun. so kudus.
we should all game.
P.S.
forgive my grammar 😛
