Xbox v PlayStation: Giants clash over Call of Duty
Xbox owner Microsoft has hit back at claims its decide to buy the maker of Call of Duty may unfairly affect its rivals, including Sony, which owns PlayStation.
Microsoft wants to shop for Activision Blizzard, which also makes Overwatch and Candy Crush, for $68.7bn (£59.2bn).
The UK watchdog looking into the plan has said Microsoft could use Activision games to "out-compete" its rivals.
Microsoft said it still hoped the deal would be closed by June 2023.
Competition regulators in Saudi Arabia and Brazil have already approved it.
But last month, the Competition and Markets Authority announced it might be asking an independent panel to look into the proposal.
Activision Blizzard is one among the world's largest video game developers and publishers, and therefore the Call of Duty franchise has attracted millions of players.
And the CMA suggested buying it could allow Microsoft to monopolise top games such as Call of Duty by making them available primarily on Xbox consoles, PCs and Game Pass, its cloud gaming service.
Xbox exclusives
In a detailed account of its decision to launch an in-depth investigation, published today, the CMA says that "Call of Duty is sufficiently important that losing access thereto (or losing access on competitive terms) could significantly impact Sony's revenues and user base".
It also said that "Microsoft has followed this approach in several past acquisitions of gaming studios, where it made future game releases from those studios exclusive in consoles to Xbox".
Microsoft says it's committed to keeping Activision's existing titles, including Call of Duty, available on the PlayStation.
But future titles might be treated differently.
Microsoft already owns 23 games makers, including Minecraft maker Mojang, and Fallout and Skyrim creator Bethesda.
Bethesda's upcoming Starfield game will now be an Xbox and PC exclusive, and therefore the CMA suggested that this could also be the case for the studio's Elder Scrolls VI, supported Microsoft's public statements.
Microsoft says:
there were 280 PlayStation-exclusive games in 2021 (Sony claims many of these came from small studios) and Sony itself has chosen to block the Games Pass platform from the PlayStation.
Microsoft lacks mobile gaming content, and Activision owns Candy Crush Saga, one among the most played mobile games.
the CMA is taking Sony's side "without the acceptable level of critical review" and "over-estimating" the power of Call of Duty to single-handedly disrupt the games industry.
And, during a report seen by BBC News, Microsoft calls the CMA's concerns "a novel theory of harm, unsupported by precedent, economic literature or the evidence".
In a statement, Sony said the firm believes the deal is "bad for competition, bad for the gaming industry and bad for gamers themselves.
"This deal would give Microsoft's Xbox ecosystem a singular combination of tech and content, and hence a dominant position in gaming, with devastating consequences for consumers, independent developers, and Sony itself," it added.
