Gamers' lawsuit against Microsoft over Activision deal dismissed.

A private consumer antitrust lawsuit against Microsoft over its proposed $69 billion purchase of Activision Blizzard has been dismissed by a federal judge in San Francisco. The plaintiffs have been given 20 days to refine their legal challenge. The judge ruled that the lawsuit lacked allegations supporting the claim that the proposed acquisition would harm market competition. The decision does not affect the U.S. Federal Trade Commission's regulatory challenge to the largest-ever gaming industry deal.
