Il gioco assedia la città. Critical City Upload e il pervasive game

City and Game. What dynamics do activate when playful practices become part of the urban fabric by changing the perception of space and time of social interactions? The following paper introduces a reflection between urban dimension and “social games”, activated and developed by the citizens for the city. From resemanticization practices to urban interaction between playful space and digital space: new mobile technologies and new media have given players more tools to interact with the urban territory through the application of geolocalization, creating a category of devices called locative media. The city rediscovers the playful dimension within that space of their city and create new forms of interaction with it through playful practices that are no longer disconnected from the experience of everyday life but are integrated and shaped it. In particular, we will analyze one of the pervasive games that have caught on in Italy, Critical City Upload, devoted to sustainable urban transformation and the rediscovery of and for social mobilization
