I think this should be treated as a serious suggestion.
Obviously I don't want my Avatar throwing his club away or punching the ground when his ball rolls slightly into the rough. And equally, I don't want violent fist pumping when he rolls in a 4-footer for birdie (as rare as that is).
Of course, I don't want him raising his hand to an imaginary crowd, either.
All I want is that every once in a while, he just nods his head contently, looks at his club in dismay or gives a little fist pump according to what he's just hit.
I feel it would just add another element of realism and emotion to this game.
Jack.
