Suppose you have a specific experience or method of playing and then build a game so that it reliably creates that experience. Or maybe you play a game in certain way and want others to be able to do so, and to accomplish this you rewrite and possibly redesign the game you are playing to be accessible to outsiders in the way it is to you.
On the other hand, suppose you play in a certain way and build or tweak a system so that it supports you as well as is within your reach. Maybe you even write the results and publish them. (It might be called a fantasy heartbreaker or a set of house rules.)
The second method is not geared towards creating legible documents. The text is generally incapable of teaching the method of play that works so well for the designers. The first method requires very much writing and thinking that is mostly wasted effort if you are simply designing for your own play.
