The greatest controller ever made for hardcore gamers.
Microsoft hit the ball out of the park with its Xbox 360 controller, which became an industry standard, and has widely been hailed as the greatest controller ever made. With the Xbox One, the Xbox 360 controller seems to have been improved upon. People who were afraid that perfection cannot be improved upon, only messed with, can rest easy. As the above video that takes us behind the scenes with the Xbox One controller shows, Microsoft seem to know what they are doing, at least on the controller front.
From the improved Dpad to the subtly enhanced ergonomics, from the better force feedback to the reduced deadzone in the new analog sticks, from Kinect functionality to increased sensitivity, the video talks to us about it all, while also talking about some under the hood changes. It looks, really, like an improvement on a design that was already perfect: in other words, it should be the de facto controller for the upcoming generation, just like the Xbox 360 controller was before it.
