Chris I guess you got a friend to write this thread for you?
Strategy games like Command & Conquer and similar would be ok for you. Pain in the butt when trying to make groups of units and switching between them.
But point and click adventures usually only need a mouse to operate also.
I dont mean to pry is it one hand that is damaged or both? Would be a shame if both, hope things work out for you and you find what your looking for
