Microsoft has encountered a lot more hurdles than it probably expected in its attempted acquisition of Activision Blizzard. For starters, the deal was blocked by the Federal Trade Commission (FTC) last year, which has sued Microsoft due to concerns over competition in the gaming industry. Microsoft is pretty confident that it will win in court, especially given that the EU has now given the deal the green light. However, the UK’s Competition and Markets Authority (CMA) is proving to be much more of a headache for the company. The CMA followed the FTC’s example and blocked the acquisition last month, on the basis that the deal could “alter the future of the fast-growing cloud gaming market”. Unlike the FTC’s lawsuit, there’s very little that Microsoft can do to push the deal through as it stands that would satisfy the CMA, so it’s possible that Microsoft could simply refuse to sell Activision Blizzard games in the UK to get around this issue.
