Microsoft’s practices regarding Xbox Game Pass have been fairly controversial, and it potentially just got much worse as the Federal Trade Commission gets involved.

Earlier this month, Microsoft announced price increases and a host of other changes to their premiere subscription service for console and PC. In addition to the price increases, a new tier will be introduced that doesn’t include day-one releases. The announcement didn’t go over well with consumers, prompting them to turn to resellers to get Game Pass codes. Now, the Federal Trade Commission is getting involved, today writing a letter to the United States Court of Appeals for the Ninth Circuit to argue against the company.
