Here is the practice screen. You hit a real ball with your own clubs (or the clubs provided) into a cloth screen projecting a driving range. The computer can show you all sorts of things that I don't understand about your swing, including a video image of your actual swing so you can see for yourself.
Once you've had your fill of practice, you can go to the actual (virtual) golf course. You can pick from various real courses from around the world of varying difficulty. Then you play your game.
p.s. Sorry lefties, you're out of luck here. A co-worker of mine was very distressed by this detail...
