Ooooh, looks like somebody just got 50 kills with the shotgun in Bioshock infinite. I remember getting that trophy.
This is a video of PBS 'Game/Show' host Jamin Warren discussing why killing things is such a central concept in so many video games. I'd be lying if I told you I watched all nine minutes of it, but that's only because I know why killing is such a fundamental mechanic in video games: it's illegal in real life, and prison sucks.
Hit the jump for the video.
Thanks to DustyD, who argues video game violence has actually led to a decrease in real life violence because people have an opportunity to get their anger and frustration out in a virtual world instead of choking their roommate.
