MAGFest Gaming Intellectuals - Video Game Ethics

Every year, Scott and I attend MAGFest not just to lecture, but also to sit as panelists alongside the rest of the MAGFest "Gaming Intellectuals" on various gaming topics.

Is it truly ethical to design a game to be addictive, or is "addictiveness" simply a sign of good design? Do games change us in more ways than we might realize? Is regulation on the horizon (as we have already seen arising in Japan), a good idea, or even truly possible? How are games different from other media?
