When a person playing a video game is so involved, so focused that they only have sights for the screen, then maybe, just maybe, they will get “the glow”. You know the glow
when you see it. When someone has the glow, they are so in the zone that any outside interruption will throw them completely off, and they could respond with violent repercussions.
The first recorded time someone had the glow was in Hollywood,
California in 1999 when Billy Mitchell completes the first-ever
perfect game of Pac-Man.
