Many people have suggested this before but so far, nothing has been heard of...
I think the best idea I've seen is to have a putting Blitz game (i.e., exactly the same as a Blitz, but with putting only)
Another idea that they could incorporate would be a driving distance/aiming game....i.e. another Blitz type game, but instead of aiming for the pin, you aim to hit either a certain yardage (it would teach people that drives don't HAVE to be hit full power), or to aim for a certain spot on the fairway
If anyone has ever played the golf game on Wii Sports, then something similar to the target practice on there might be a good idea...
