Does this come close to answering your question?
Yes! Now, you were a bit vague, but that's exactly it.
Some examples of what makes the game fun for me:
"Discovering" a contour or ground element that makes it possible to play a shot differently than I otherwise might.
The sense of self-mastery I feel when a horrid shot does not, in turn, lead to another horrid shot.
The occasional amazing shot I get to hit, especially if it has come after horrid shot.
All the light-hearted talking I get to do with the people I'm playing with, which stands in stark contrast to the grind that life can be.
Laughing at my brothers alternately terrific and horrible shot-making and luck (much worse than mine).
The occasional mental picture I get to snap when I see something compelling. It could be a huge bunker that dwarfs the person standing in it, my brother David's ball 6-inches immediately to the left of a tree (he's a lefty), David flipping over a 7-iron and hitting it right-handed, the light filtering down through the boughs of the pine forest in which my ball currently resides...you name it.
I could go on, but hopefully this gets to the point.
