drew writes "ACM is hosting a two-day videogame symposium on July 29-30 in 2006, co-located with SIGGRAPH 06 in Boston, MA, USA. The symposium will consist of keynotes, panels and papers. In addition, a 'Hot Games' session will preview unreleased titles from major game companies and indie developers."
