Apple engines are so bad that Cocos2D-x is basically a copy of their features, using C++ instead of Objective-C/Swift, one of the engines that Google and Microsoft give first class on their platform SDKs.

Not every game engine needs to be a bullet point list copy of Unreal capabilities.

And no I am not joking, contrary to many here, I had a past life in demoscene, been a former IGDA member, previous GDCE attendee (London and Cologne), have been inside a couple of known AAA publishers and have kept my contacts from them.
