French sociologist Roger Caillois, in his book Les jeux et les hommes (Games and Men)Caillois, Roger (1957). Les jeux et les hommes. Gallimard. , 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 | |
| governed by rules: the activity has rules that are different from everyday life | |
| fictitious: it is accompanied by the awareness of a different reality |
Computer game designer Chris Crawford attempted to define the term game using a series of dichotomies:
- 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.)
- A piece of entertainment is a plaything if it is interactive. Movies and books are cited as examples of non-interactive entertainment.
- 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.
- 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.)
- 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, and which is designed to make money for the creator.
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.” (Greg Costikyan) | |
| “An activity with some rules engaged in for an outcome.” (Eric Zimmerman) |
