REDMOND, Dec 22 (AFP) - Microsoft Corp said on Thursday that its $69 billion bid to buy "Call of Duty" maker Activision Blizzard would benefit gamers and gaming companies alike.

Microsoft made the argument in a filing aimed at convincing a judge at the U.S. Federal Trade Commission to allow the deal to proceed, after FTC commissioners said the merger would hamper competition in the gaming industry in a complaint this month aimed at blocking the deal.
