Prof. Dmitri Williams, one of the leading academics in the gaming space, who was an expert witness at the U.S. Senate on the constitutionality of game banning laws, held a roundtable on game addiction at GDC. Williams referenced Carnegie Mellon University A. Fleming Seay's research on addiction in an MMO context.
The addiction, defined as "problematic use" by Seay, is when an entertainment product dominates and displaces other behavior,
causes conflict and not playing causes anxiety.
