It is a discussion that crops up from time to time: what is a game? This would be a fairly academic definition question, were it not that it finds a much larger battleground mostly outside academia, where consumers and critics of video games are the participants.
The direct catalyst for the most recent iteration of this discussion was the release two days ago of Proteus, a game developed by Ed Key and David Kanaga. This work, as I briefly explained in my piece on Noctis, is all about free exploration of an island and its flora and fauna, about building a soundtrack by moving around. It is limited in its interactivity compared to many other video games, and this has sparked the discussion on whether or not Key and Kanaga are right to refer to Proteus as a game.
