Head of Xbox Phil Spencer shared the filing on Twitter, which was a declaration by Kevin Gammill, the general manager of gaming developer experiences for Microsoft, that describes how harmful this potential move by Apple could be for Microsoft and the gaming industry as a whole.
Gammill’s main point stems from the fact that Epic Games’ Unreal Engine is “critical technology for numerous game creators including Microsoft.” While there are many studios who develop their own game engines, Unreal Engine remains one of the top choices for those who don’t have the resources or capabilities to do so.In Microsoft’s view, there are very few other options for game engines that offer “as many functionality as Unreal Engine across multiple platforms, including iOS.”
Furthermore, Microsoft has an “enterprise-wide, multi-year Unreal Engine license agreement and has invested significant resources and engineer time working with and customizing Unreal Engine for its own games on PC, Xbox consoles, and mobile devices (including iOS devices).”
This is the case for other developers in the gaming industry, and if Apple were to deny Epic access to Apple’s SDK and other development tools, it would “place Unreal Engine and those game creators that have built, are building, and may build games on it at a substantial disadvantage.”
