ShatterZone is an immersive, first-person multiplayer action game where players control animated avatars to compete in high-stakes combat. Players are awarded virtual tokens and peer praise within the game's live-chat lobby for executing highly destructive moves and "eliminating" opponents' avatars. A longitudinal study tracked children who played ShatterZone for more than 10 hours a week from age 8. By age 12, these children demonstrated significantly higher rates of physical and verbal aggression in school playgrounds compared to a control group. This aggressive tendency remained significant even after controlling for baseline childhood temperament and parental discipline styles. In later adolescence (age 16), follow-up surveys showed that these individuals had lower levels of empathy, higher acceptance of interpersonal violence, and frequently modeled their real-world confrontational styles on their favorite in-game avatars.
