During Fall 2012 I presented with Marina Kobayashi at the San Francisco Game Design Conference. Not to be confused with GDC, the Game Design Conference was a smaller event that focused solely on aspects of game design.
The talk defines Games User Research (GUR), and includes two perspectives on practicing GUR at different companies with drastically different budgets. Furthermore the talk provides concrete examples on how to use GUR with different platforms, genres, and with different target audiences.
The talk is available on Slideshare.
