Another presenter at the GDC by Clint Hocking made mention of some of our reading! I love it when I get to read topical and relevant material for a class!!!

"An excellent starting point for looking deeper into immersion is Rules of Play by Eric Zimmerman and Katie Salen, which was an invaluable resource for me in preparing the talk (in particular refer to Unit 3: Play, Games as the Play of Simulation) - thanks Eric and Katie."
