The Competition Appeal Tribunal in London has authorized a class action lawsuit against Valve Corporation, which alleges anti-consumer practices related to overcharging British customers and manipulating PC game prices on its Steam platform. The claims in the lawsuit exceed £100 million, and the tribunal's unanimous decision allows the case to proceed through the UK legal system. Valve's attempt to dismiss the class action was unsuccessful, and a trial date has not yet been set. Valve has not publicly commented on the proceedings.
