I don’t really understand why Microsoft is dragging their heels with adding UWP to Unreal. Fable Legends is built in UE4. The next Gears of War will be built in UE4. Microsoft is obviously going to make them both available on Windows 10 / UWP so what are they waiting for? If PC gaming is so important to them (Microsoft makes big Xbox-on-PC push with 4K, 60 fps Forza 6 Apex | Ars Technica) then they should make adding UWP to UE4 a priority.
