Microsoft’s Kevin Gammill, general manager of Gaming Developer Experiences, called Epic’s Unreal Engine “critical technology” in a filing at the weekend [PDF] in support of Epic’s motion for a temporary restraining order to prevent Apple from terminating its developer account.
Referring to the statement, Xbox supremo Phil Spencer tweeted yesterday to say “ensuring that Epic has access to the latest Apple technology is the right thing for gamer developers and gamers.”
Gammill’s argument is that Unreal Engine, a cross-platform runtime and development environment, is “critical technology for numerous game creators including Microsoft”, and that “there are few other options available for creators to license with as many features and as much functionality as Unreal Engine.”
“If Unreal Engine cannot support games for iOS or macOS, Microsoft would be required to choose between abandoning its customers and potential customers on the iOS and macOS platforms or choosing a different game engine when preparing to develop new games,” said Gammill in the filing. He added that it would also harm those with games in “later stages of development” using Unreal Engine, and already-launched games for which Unreal Engine could no longer be updated or receive security patches.
