According to a document from the EU, antitrust inspectors are asking game developers whether Microsoft will be motivated to prevent competitors from playing Activision Blizzard's top-grossing titles.

The preliminary verdict on whether to approve Microsoft's proposed $69 billion acquisition of Activision is scheduled on Nov. 8 from EU antitrust regulators.

The EU paper reveals that the EU competition enforcer questioned if Activision's vast user database would offer the American software company a competitive edge in the creation, publication, and distribution of computer and console games.

Microsoft will be able to better compete with giants Tencent and Sony thanks to the upcoming acquisition, which will be the largest in the gaming sector.

The European Commission is anticipated to launch a four-month inquiry following its decision next month, highlighting regulatory worries about Big Tech acquisitions.

If the agreement would effect their ability to negotiate the conditions for selling console and PC games via Microsoft's Xbox and its cloud game streaming service Game Pass, it was questioned of game developers, publishers, and distributors.

In addition, regulators wanted to know if there would be enough substitute vendors in the market after the transaction and if Microsoft would elect to make Activision's games solely available on its Xbox, Games Pass, and cloud game streaming services.

They inquired as to whether such exclusivity provisions would strengthen Microsoft's Windows operating system in comparison to competitors and whether the addition of Activision to its PC operating system, cloud computing services, and game-related software tools gives it a competitive edge in the video gaming sector.

They questioned the significance of the Call of Duty series for game publishers of consoles, PC third-party multi-game subscription systems, and cloud game streaming services.

The questionnaire, which had roughly 100 questions, asked which of the competitors, including Facebook Gaming, Google Stadia, Sony's Playstation, Nvidia's GeForce Now, and Amazon Luna, may be the most alluring after the deal.
