In order to promote the implementation of Blizzard's acquisition, Microsoft recently told the UK Competition and Markets Authority that Sony's PlayStation-exclusive games are superior to Xbox-exclusive games in both quantity and quality.
Microsoft cited Metacritic data showing that the average score for the top 20 PlayStation exclusives in 2021 was 87/100, while Xbox exclusives averaged 80/100 over the same period.
In addition to the higher scores of PS exclusive games, Microsoft also pointed out that PlayStation exclusive game sales accounted for 10-20% of all PlayStation games, while Xbox exclusive games accounted for only 0-10%.
In a PDF document submitted to the U.K. Competition and Markets Authority, Microsoft emphasized that it will not remove Activision titles from PlayStation until the acquisition is completed. But no matter how stressed Microsoft is on this issue, regulators are still concerned.
Activision Blizzard has launched popular classic games such as Overwatch, Diablo, Call of Duty, World of Warcraft, Candy Crush and StarCraft, and has a very large influence in the game circle. While the U.K. has decided to review Microsoft's acquisition of Activision, several countries, including Brazil and Saudi Arabia, have allowed the deal to go ahead.
