The Game

A game is a structured or semi-structured activity, usually undertaken for enjoyment and sometimes also used as an educational tool. Games are generally distinct from work, which is usually carried out for remuneration, and from art, which is more concerned with the expression of ideas. However, the distinction is not clear-cut, and many games are also considered to be work or art.

Key components of games are goals, rules, challenge, and interactivity. Games generally involve mental or physical stimulation, and often both. Many games help develop practical skills, serve as a form of exercise, or otherwise perform an educational, simulational or psychological role.
Known to have been played as far back as the 30th century BC, games are a universal part of human experience and present in all cultures.The Royal Game of Ur, Senet and Mancala are some of the oldest known games.

Definitions

Ludwig Wittgenstein
Ludwig Wittgenstein was probably the first academic philosopher to address the definition of the word game. In his Philosophical Investigations, Wittgenstein demonstrated that the elements of games, such as play, rules, and competition, all fail to adequately define what games are. He subsequently argued that the concept "game" could not be contained by any single definition, but that games must be looked at as a series of definitions that share a "family resemblance" to one another.

Roger Caillois

French sociologist Roger Caillois, in his book Les jeux et les hommes (Games and Men), defined a game as an activity that must have the following characteristics:

-fun: the activity is chosen for its light-hearted character
-separate: it is circumscribed in time and place
-uncertain: the outcome of the activity is unforeseeable
-non-productive: participation is not productive
-governed by rules: the activity has rules that are different from everyday life
-fictitious: it is accompanied by the awareness of a different reality

Chris Crawford

Computer game designer Chris Crawford attempted to define the term game[4] using a series of dichotomies:

1-Creative expression is art if made for its own beauty, and entertainment if made for money. (This is the least rigid of his definitions. Crawford acknowledges that he often chooses a creative path over conventional business wisdom, which is why he rarely produces sequels to his games.)

2-A piece of entertainment is a plaything if it is interactive. Movies and books are cited as examples of non-interactive entertainment.

3-If no goals are associated with a plaything, it is a toy. (Crawford notes that by his definition, (a) a toy can become a game element if the player makes up rules, and (b) The Sims and SimCity are toys, not games.) If it has goals, a plaything is a challenge.

4-If a challenge has no “active agent against whom you compete,” it is a puzzle; if there is one, it is a conflict. (Crawford admits that this is a subjective test. Some games with noticeably algorithmic artificial intelligence can be played as puzzles; these include the patterns used to evade ghosts in Pac-Man.)

5-Finally, if the player can only outperform the opponent, but not attack them to interfere with their performance, the conflict is a competition. (Competitions include racing and figure skating.) However, if attacks are allowed, then the conflict qualifies as a game.

Crawford's definition may thus be rendered as: an interactive, goal-oriented activity, active agents to play against, which any player (including active agents) could interfere one another.

Crawford also notes (ibid.) several other definitions:

-“A form of play with goals and structure.” (Kevin Maroney)
-“A game is a form of art in which participants, termed players, make decisions in order to manage resources through game tokens in the pursuit of a goal.”

-“An activity with some rules engaged in for an outcome.”

Gameplay elements and classification

Games can be characterized by "what the player does."This is often referred to as gameplay, a term that arose among computer game designers in the 1980s but as of 2007 is starting to see use in reference to games of other forms. Major key elements identified in this context are tools and rules which define the overall context of game and which in turn produce skill, strategy, and chance.

Tools

Games are often classified by the components required to play them (e.g. miniatures, a ball, cards, a board and pieces or a computer). In places where the use of leather is well established, the ball has been a popular game piece throughout recorded history, resulting in a worldwide popularity of ball games such as rugby, basketball, football, cricket, tennis and volleyball. Other tools are more idiosyncratic to a certain region. Many countries in Europe, for instance, have unique standard decks of playing cards. Other games such as chess may be traced primarily through the development and evolution of its game pieces.

Many game tools are tokens, meant to represent other things. A token may be a pawn on a board, play money, or an intangible item such as a point scored.

Games such as hide-and-seek or tag do not utilise any obvious tool. Rather its interactivity is defined by the environment. Games with the same or similar rules may have different gameplay if the environment is altered. For example, hide-and-seek in a school building differs from the same game in a park; an auto race can be radically different depending on the track or street course, even with the same cars.
