And they're not great.

The verdict seems to be that if you don't have 8-10 feet of space between you and your TV, it's just not going to work for you. If you don't have even more than that, you can say goodbye to multiplayer. If you do have enough space, it may not work unless you adjust your lighting, change your clothes, and move your furniture. Once that's not an issue, the interface is unreliable via voice control and unnecessarily slow via motion control. Finally, the most important part of this, the games, are not only tiring to play, but don't live up to the visual quality you'd expect from a High Definition console because of the RAM needed for Kinect alone. Some of them are said to be fun, but the novelty seems to wear thin fairly quickly. The biggest problem, however, is the intrinsic fact that you can't actually move your character, you can only control what they do while standing still, or on rails at a speed the game determines.

It just doesn't seem like a viable interface for video games.

Kotaku seemed to be the most positive, saying it's amazing but you can wait for it, all the while acknowledging that the current firmware functionality and software lineup doesn't deliver on its potential.

Joystiq and Engadget both knocked it for its difficulty and sometimes failure in working, and most of the games got pretty bad grades.

ArsTechnica seemed the most brutally honest - the games were fun, but everything else said about it pretty much condemned the thing.
