I have cerebral palsy. i beat Elden Ring multiple times in NG+ with literally one hand and a ps4 controller. i have also played against other players in the game and won.

if you have eyes to see and five working fingers, you can learn to play video games just as well as someone who does not have a disability. Might take you some time, took me years, but you'll eventually learn, and come up ways to make it even easier for yourself.
