There is nothing about AEP that would make the required porting process either easier, or harder. Extended capabilities are something to think about when you actually have a functioning port on the target platform. Until then, these extensions are mostly for big-name engine vendors, so they can have feature parity for their products across platforms.
Not that it matters, given the irony of the demo: All those fancy graphics, yet the focus is on “Tappy Chicken”.
If history has taught us anything, it’s that graphical fidelity is made virtually irrelevant by compelling gameplay. Minecraft, Braid, Starseed Pilgrim and many other games have proven as much.
As “high-end” graphics become more common, they will become even more boring (especially for casual players, who dominate mobile markets).
