While finite games are externally defined, infinite games are internally defined. The time of an infinite game is not world time, but time created within the play itself. Since each play of an infinite game eliminates boundaries, it opens to players a new horizon of time. For this reason it is impossible to say how long an infinite game has been played, or even can be played, since duration can be measured only externally to that which endures. It is also impossible to say in which world an infinite game is played, though there can be any number of worlds within an infinite game.
