Much of what Gee has to say here is similar to what he said in his book in 2004. He adds here the designation “semiotic social space” to name the types of spaces he described in his book. He emphasizes that generators create signs that make up the content of the game. These signs can be viewed as internal, the original content itself and its design, or external, the individual and social practices surrounding the content and how people “organise their thoughts, beliefs, values, actions and social interactions in relation to the signs made available” in the content (p. 219).
