During the first day of Build, Microsoft's developer conference, the OS giant announced that they would be giving a 95 percent revenue share to developers – with some caveats.
The new fee structure, changing from a traditional 70/30 split, only applies to apps on Windows 10 PCs, Surface, Mixed Reality devices, and Windows phones. That means things like the Xbox will remain at the previous revenue share. It also only covers non-game apps on the Windows store, which means it probably won't be luring games from Steam anytime soon.
However, a 95 percent revenue share (85 percent if purchased from the Windows store) is still by far the biggest developer share in the industry, and could make huge waves if Microsoft applied it to game developers on even a promotional basis. Microsoft's biggest critic of the Windows store, Epic Games' Tim Sweeney, even applauded the news on Twitter as healthy competition.
The industry would be massively changed if services starting upping the share above the standard 70 percent. It would probably take a company with deep pockets and doesn't mind the revenue loss, though, so Microsoft is as good a choice as any.
