Apple has a gaming strategy. iPhone makes developers too much money to ignore, and since adopting in-house silicon across all product lines their handhelds, tablets, laptops and desktops all use the same APIs and CPU/GPU cores.
If you target iPhone, there is not much additional work to add a keyboard/mouse/gamepad UI to target the rest of their ecosystem.
We've started seeing Console games get ported to iPhone, which I don't think anyone was expecting a couple of years ago.
