High dexterity games like first person shooters are particularly challenging for many people with physical disabilities. On the other end of the spectrum are turn based games like chess and MTG Arena, that can be done by practically anyone.

To my knowledge, Psyonix is working together with AbleGamers to optimize Rocket League for adaptive gear, like the Xbox Adaptive Controller. Also, recently LogitecG started organizing Rocket League tournaments for disabled gamers with total prize pool of $50k. Honorable mentions go to SpecialEffect, Intel, Razer and a handful of smaller developers.
