According to reports, the multiplayer video game Fortnite may face a class-action lawsuit in Canada after two parents of teenage sons filed last week alleging the video game can be as addictive as cocaine. The Montreal-based law firm, Calex Legal, filed a motion in Quebec Superior Court on Thursday on behalf of the 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. The lawsuit, which has yet to be approved by the court, seeks to hold the U.S.-based video game publisher Epic Games Inc., 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 “a gaming disorder,” a disease. Fortnite is free to use but requires players to purchase virtual currency to buy accessories and other add-on for their virtual players.
