The maker of Fortnite may face a class-action lawsuit in Canada after two parents of teenage sons alleged last week the company purposely designed the multiplayer video game to be as addictive as cocaine, according to reports. The Montreal-based law firm, Calex Légal, filed a motion in Quebec Superior Court Thursday on behalf of two parents who approached the firm separately about their 10- and 15-year-old sons, who they claim developed a severe dependence on the game, USA Today reported. The suit, which has yet to be approved by the court, seeks to hold the U.S.-based video game publisher Epic Games Inc., as well as its Canadian affiliate based in British Columbia, accountable for using psychologists and statisticians “to develop the most addictive game possible.” The lawsuit also noted that the World Health Organization last year declared video game addition, or “gaming disorder,” a disease. The game is free to use but requires players purchase virtual currency to buy accessories and other add-ons for their virtual players. “Children are particularly vulnerable to this manipulation since their self-control system in the brain is not developed enough.” More here.
