Grand theft algorithm: purposeful play, appropriated play and aberrant players

This paper explores ideas about 'appropriated play' within computer games. It identifies different forms of 'purposeful' and 'aberrant' playing and proposes a model of players' motivations. This will enable a discussion about the experience of games players who resist the norms of 'purposeful' or ludic play, while finding reward in their explorations of game possibilities. It provides a new vocabulary for discussing playing outside of the game world, as a way of understanding some of these actions as more than 'cheating'.
