Any 1 handed games for pc?

I am a competitive shooter enjoyer and there was a pain in my aiming arm for 2 months it wasn't much so i ignored it sometimes taking breaks. But recently I armwrestled with few of my buddies and when I tried to play shooters again it really hurt. So I don't think I will be playing any fps or aiming games for a while. Any 1 handed game suggestions? Could be strategy games, story games. Thanks!

side note: can't buy any 1 handed controllers ;-; thx!
