The United Kingdom’s antitrust regulator is worried that Microsoft’s blockbuster buy of Activision Blizzard might create a monopoly within the nascent cloud gaming house. The Competition and Markets Authority (CMA), which started investigating the deal again in July, says that it’s not but reassured by the guarantees Microsoft has made to get the deal carried out. It feels that, as soon as Activision is part of Microsoft, the Xbox maker might use its “control over popular games like Call of Duty and World of Warcraft” to “harm rivals” by boxing them out of entry to standard titles. Microsoft has already publicly dedicated to not hoard exclusives, (and stated that Actiblizz’s library is not all that anyway) however candy phrases haven’t appeased the officers.

In a press release, it stated that it was giving Microsoft and Activision 5 days to submit proposals that might handle its considerations. If these didn’t cross muster, nevertheless, then the workplace will open a prolonged “Phase 2” investigation involving an impartial panel to scrutinize the deal in higher depth. That will probably delay any completion of the deal, which might then solely be rubber-stamped if regulators have been satisfied that the deal wouldn’t trigger a “substantial lessening of competition.” It’s probably that, no matter occurs, Microsoft might want to decide to not utilizing its rising clout to harm different corporations within the house by depriving them of key franchises.

Microsoft’s gaming chief Phil Spencer has already responded to the announcement, affirming the earlier pledge to not pull Call of Duty from PlayStation, for example. Spencer pointed to the cross-platform enchantment of Minecraft, a title Microsoft bought in 2014, as proof of the corporate’s good religion. Activision CEO Bobby Kotick revealed an open letter to staff, saying that the corporate will “fully cooperate” with regulators, that are taking “appropriate” steps to make sure that there aren’t any dangers to competitors.
