An anonymous reader writes from a report via Bloomberg: Valve's Counterstrike: Global Offensive game is being sued for its role in the multibillion-dollar gambling economy that has fueled the game's popularity. Michael John McLeod filed a lawsuit Thursday in the U.S. District Court in Connecticut alleging that Valve violated gambling laws and engaged in racketeering with a handful of off-shore gambling companies. McLeod, who has been gambling on CS:GO since 2014, is asking for class-action status for the suit. The suit was first reported by Polygon and doesn't give a specific request for damages, nor does it say how much money he lost by betting on the site. According to Bloomberg: "Valve provided for money, technical support, and advice to such websites as CSGO Lounge and Diamonds, which take bets, and OPSkins, which runs a market where virtual goods are traded and can be redeemed for cash." Valve has yet to respond to the suit.
