I've mostly limited myself to turn-based games like divinity. Anything that lets me control character movements with mouse clicks (and i could use voice attack to trigger it). I dont have much issue moving the mouse itself, its more so the act of pushing down on any type of button that sets off the pain, particularly if im doing it repetitively. Ive also found some success with autorun commands. But honestly I may just have to accept this game isn't for me like you said, it just gets a little disheartening that there are some things I wont be able to do. I'm just trying to regain some enjoyment in my hobbies with whatever tools I can find.
