Part Nine of the GAMBIT Summer Summit 2011 Videos, "Afterland Revisited. A Theory-Based Game Development Research Circle" is a lecture from GAMBIT Researcher and Summit Organizer Konstantin Mitgutsch about his Summer 2010 game, "Afterland". Every summer at the Singapore-MIT GAMBIT Game Lab, students from Singapore and the US work with GAMBIT researchers and development teams on novel game concepts, and visiting researchers spend that time research gaming related topics across a variety of fields. Back on July 6th, 2011, we drew back the curtains in the middle of the summer to provide insights into our current game development and research activities during the inaugural GAMBIT Summer Summit.
