my bad , hope you get better and you can use you hand soon like you used to , about one hand option , maybe will be possible, dunno , maybe you could play. Someone before me mentioned you could play with pedals , and i could say the same yet still i am aware there are more options but dunno what , i would say a mouse yet then noone has enough money for 1 dedicated mouse , Im talking about razers Naga Trinity just because it has like 12 side buttons so yeah sounds weird using side buttons to play games and i am aware that mouse is pretty expensive , i personally dont use it because here where i live its pretty expensive , so i wont complain if is it a bad mouse or good mouse ill just mention it as i know it has 12 side buttons.
