  abstract  = {In a common description, to play a game is to step inside a concrete or metaphorical magic circle where special rules apply. In video game studies, this description has received an inordinate amount of criticism which the paper argues has two primary sources: 1. a misreading of the basic concept of the magic circle and 2. a somewhat rushed application of traditional theoretical concerns onto games. The paper argues that games studies must move beyond conventional criticisms of binary distinctions and rather look at the details of how games are played. Finally, the paper proposes an alternative metaphor for game-playing, the puzzle piece.},

  abstract  = {Jesper Juul has convincingly argued that the conflict over the proper object of study has shifted from "rules or story" to "player or game." But a key component of digital games is still missing from either of these oppositions: that of the computer itself. This paper offers a way of thinking about the phenomenology of the videogame from the perspective of the computer rather than the game or the player.},

  abstract  = {One of the informal properties often used to describe a new virtual world is its degree of openness. Yet what is an "open" virtual world? Does the phrase mean generally the same thing to different people? What distinguishes an open world from a less open world? Why does openness matter anyway? The answers to these questions cast light on an important, but shadowy, and uneasy, topic for virtual worlds: the relationship between those who construct the virtual, and those who use these constructions.},
