In September 2013, Thompson expressed his hatred of "Grand Theft Auto V" during a series of e-mails exchange with GameZone writer Lance Liebl during its launch week. The game happened to launch the day after the Washington Navy Yard shooting. Traditional media outlets such as Fox News and MSNBC sought out to find proof that violent video games, such as "Grand Theft Auto V", had a role in the brutal killings. GameZone responded by writing an article that disagrees with this. These caught Thompson's attention, who then sent an e-mail to the site. "Look, Lance," he wrote in an email, "The American Psychological Association has established a causal link between these games and increased aggression. The Dept. of Defense uses them for that purpose." Liebl responded by offering Thompson a chance to come on the site and explain his stance, which he refused, describing gamers as "too brain-impaired to get it."
