Internal Structure of a Game

I want to take a cut at the internal structure of a game to provide some vocabulary for discussing aspects of a game and to provide some distinctions between a game of some of the related phenomena.

First, a game must have a deciding factor. The deciding factor determines who, if anyone, has won the game. For example, in Chess, the deciding factor is having a King in Check. In football, it is the team with the most points. In golf, it is the person with the least points. There may or may not be constraints on the deciding factor. In football, for example, there is a time limit whereas in many games there is not.

Second, if the deciding factor is numeric, the game must have goals which are both complete units of activity and ways to accumulate points. So, scoring in football, getting a ball in a hole in golf, or exposing your winning hand in poker would be examples of goals.

On the way to achieving a goal there may be objectives the satisfaction of which helps you to achieve the goal but for which you do not get points. You may get credit for objectives in game statistics. But, the satisfaction of the objective does not contribute to the deciding factor.
Depending on the complexity of the game there may be subobjectives which are smaller problems that must be solved in order to achieve an objective.

There may be contratints on how goals or objectives are achieved.

And, to borrow a term from Suits, there is a 'lusory attitude'. The point of playing the game is the inherent satisfaction one achieves through playing a game. That is, the point of the game is the game itself. So, if one is playing professional poker to earn their livelihood, it would no longer be a game under this defintion. There is an element of practicing for real life that makes a game a game. As soon as it is no longer practice but actually is real life, it is no longer game.

Those are my thoughts for now. I may change some of this as I figure out more about it.
