The Wii U has been around for a while, and isn't as fast as the PS4 or Xbox One. Still, it works fine for the games available, and its motion controller is excellent.
The Wii U starts at $300 for a unit with 8GB of storage and one motion controller. For an extra $50, you can boost the storage to 32GB.
That's a hefty price tag considering the PS4 gives you a lot more storage and speed for just $100 more. But storage and speed aren't the whole story.
I already mentioned the Xbox One's Kinect and the add-on motion control options for the PS4. But much of the time you'll be using a standard handheld controller to play.
The PS4's DualShock 4 controller has a six-axis motion sensor, touch pad, built-in speaker and a new Share button that lets players upload screenshots and live-stream gaming sessions with the touch of a button.
