I have never been able to get good at using analog sticks with FPSs. I'm so bad at it that if the game doesn't have auto-aim, I basically can't enjoy the game because I am sucking so badly.

The problem for me is that the analog sticks are velocity-based; ie. you don't get to control the position directly, you can only control the first derivative of the position, the velocity. That means instead of just moving the controller where you want to go, you have to move in the direction you want to go and hold it there for just the right amount of time.

I'm amazed that so many people can do this so well, because no matter how much time I play I still suck at it. It just feels so clumsy.

So the idea of being able to use a handheld controller that isn't velocity-based really appeals to me, though I do worry a bit that the active area is so small.
