Thanks to the IGDA for its 'Culture Clash' column discussing the increasingly complex nature of heroism and villainy in videogames.

Do you enjoy stereotypical portrayals of good and evil in gaming, or do you find, as Daryl Zero needed to be told: "You realize... there aren't any 'good guys' and 'bad guys'... there are just... just a bunch of guys"?
