Arthur Protasio, the coordinator of the Game Studies project at the Center for Technology and Society (CTS) of the FGV Law School in Rio de Janeiro invited me to a colloquium on 7 December with the above title. The other speakers are the game designers James Portnow from the US, who had worked on the Call of Duty series at Activision, Guilherme Xavier, art and design director of the Brazilian studio Donsoft (Capoeira Legends) and Arthur himself. Great opportunity to present some of the games research I did in the context of the Arbeit 2.0 project. And great opportunity to visit the cidade maravilhosa again.
