Nintendo Wii U on sale Nov. 18; what you need to know

Anyone looking for multi-user gameplay can purchase a Wii U Pro Controller for about $50 from retailers such as GameStop.

Is the Wii U backwards compatible with older Wii games

Nintendo says the new console will be backwards compatible, but that functionality requires a system update that will be available on Sunday, according to IGN. The bad news is non-Wii U games will have to be played in what is called "Wii Mode" and will only work with old Wii controllers. The Wii U GamePad will reportedly not work with older Wii games.

How many games will be available at launch

There will be more than 30 games for the Wii U on Sunday including popular titles such as Assassin's Creed III, Call of Duty: Black Ops II, Batman: Arkham City, and NBA 2K13.
