"This notion of controls being crappy is ludicrous..."
I'm guessing you only game on a gamepad? If you want an example of a modern game that has absolutely horrible controls on anything but a gamepad, look at Dragon Age: Inquisition. Its controls are absolute shit on a mouse when in combat -- the first DA has fantastic controls. Despite EAware's lies, the game was designed only for a gamepad, so when it comes to mouse controls, they are downright crap and complete afterthought. This game is one of the worst offenders, but there are plenty more that are just crappy to play on a PC, because the developers really didn't bother to test/design their game for anything but a gamepad.
And I know you're questioning the parent, I wouldn't want to play some games on an Xbox, because it doesn't support a mouse... I own multiple controller, several gamepads, a HOTAS, racing wheel, and of course a good mouse. I like using the best input for the game at hand and gamepads fit a very narrow niche compared to all the games that a mouse encompasses. And I'm getting an Oculus in July and I honestly don't need the bundled gamepad, I'd prefer if I could just trade it back in for the Touch-inputs they're releasing later on -- which is how they're intending it to be played.
