“The Bad Lieutenant” is an interesting article about video game violence by Clive Thompson:
Consider our gaming history […] anti-gaming critics didn’t really explode with indignation until Grand Theft Auto 3 came along — the first massively popular modern game where the tables turned, and you finally played as a cop-killing thug. […] Why weren’t these detractors equally up in arms about, say, the Rainbow Six series? Because games lay bare the conservative logic that governs brutal acts. Violence […] is perfectly fine as long as you commit it under the aegis of the state. If you’re fighting creepy Arabs and urban criminals, go ahead — dual-wield those Uzis, equip your frag grenades and let fly. Nobody will get much upset.
And maybe not that far from the truth?
