A finite game is played for the purpose of winning, which ends the game; an infinite game is played for the purpose of continuing the play. The defining difference is not the activity but the orientation: one seeks termination through victory, the other seeks perpetuation through ongoing participation.
In finite games rules are fixed in advance and cannot change during play, because they define the conditions under which someone can win. In infinite games rules exist to keep players in the game and are changed whenever they threaten to end it, making the rules subordinate to continued participation.
No one can be forced to play a game; finite players must agree to the constraints while pretending they have no choice, a deliberate self-forgetting Carse calls 'self-veiling.' The seriousness of finite competition depends on players concealing from themselves that their participation is voluntary.
Winning a finite game confers a title that exists only in the recognition of others and refers permanently to a past moment of triumph. Because titles must be displayed and defended against forgetting, the finite winner becomes bound to repeat and protect a dead achievement rather than live forward.
Power is a finite-game concept measured by what one has won and the resistance one can overcome, and it can only be demonstrated when the game is concluded. Strength is the infinite-game capacity to keep playing and to be surprised, found in opening oneself to others rather than imposing limits on them.
Finite players move others by acting on them through force, position, or theatrical display designed to produce a predictable response. Infinite players touch others by engaging them in genuine, unscripted encounter where both parties can be changed, treating interaction as drama rather than theater.
