“I believe we need to analyze some of the video atrocities committed on PlayStation2 or Dreamcasts, or even the Commodore 64, if we need to go back that far. Teammates play each other all the time on these platforms in baseball simulations, football and other head-to-head games. This creates all kinds of bad blood when the winner is not as gracious as he could be.”
