The Wii U's bread and butter is its GamePad. Nintendo thrives on unique novelties, and the tablet-like controller fits the bill. One of its biggest perks is that it lets you play your games without a TV. If you were hoping to do that with your old Wii games, though, think again.

The Wii U is backwards compatible with the Wii, but those old games will be tied to your TV. "Wii Mode" will only work with the original system's controllers and accessories. So if you want to play Super Mario Galaxy, you'll need the classic WiiMote and Nunchuk.

Not worth the trouble

Until Nintendo releases a sequel for the Wii U, you won't see Mario Galaxy on the GamePad

This makes sense, even if it frustrates early adopters. Most Wii games used motion controls. Remapping those controls to the GamePad's accelerometer (its version of motion control) and touch screen would be a pain. In many cases, it wouldn't even make sense.

There could be some consolation. Nintendo says it will be releasing a Wii U Virtual Console, Nintendo's emulator for older games. There weren't any more details, though, so you won't likely see that at launch.
