Mean 18
http://en.wikipedia.org/wiki/Mean_18Quote: Mean 18 had two major claims to fame: it was the first computer golf game to give the golfer's point-of-view of the course, and it was the first golf game to come with a course editor that allowed players to create their own courses.
This game kept me and my dad stuck in front of the 500 for months on end. Eventually the disk broke and we spent an age trying to get another copy. Magic game.
