WGT is like 2/3 click isn't, yeah?
I think I maybe played it on my iPad?
It's really kind of archaic and overly simplified in concept. You push the mouse forward while holding down the left mouse button to set the power of the swing, The further you push the mouse, the longer the backswing. You can seemingly move the mouse at whatever pace you feel comfortable with to do this. You can surgically put the swing length at any point you want to. Then you let go of the button to start the downswing, then you have to click the left mouse button again at 6 o'clock to hit it straight, As per all the other click mechanisms out there, you'll hook or slice your shot proportional to the degree you're late or early on this final click.
This method just feels a bit retro and primitive, and all the while it's taking place in an Adobe Flash Player screen. To each their own I say, but the WGT phenomenon is one that will leave me scratching my head
