New social games are released daily, yet many of the most popular games offer very limited forms of interaction between players. This presentation answers the question: how social are social games? It goes through an analysis of 80 games, identifying the major types of interactions employed and highlighting games offering unusual social mechanics. The second part of the lecture explores how social media applications are using interaction in novel ways. Finally, the lecture will explore the range of social functions offered by social games and point to other types of interactions, enabled via social media, to encourage game designers to think beyond the boundaries of game design.
