Here’s a cool, very game-grammary approach to board game design that is inspired, as my initial game notation work was to some degree, by music.

What I arrived at was a series of “discoveries” or “conclusions” about specific models of game design that I assert can help one in the process of identifying not only problems in a game design but also what may be lacking or not present yet that could help a game reach the next level. As I arrived at these conclusions, I found that they felt very much like many of the typical principles of composition that I encountered while studying music.

The bulk of the article ends up examining a particular “atom” called the “Tri-Level Resource Exchange Model.” Atoms like these are usually termed “design patterns” in software. The article lands at identifying the number 5 as apparently very important in this model; I don’t think it is coincidence that it fits nicely in the famous 7 +/2 range.
