Finally, you can browse your neighborhood through the tiny window of your Wii U GamePad. Wii Street U is free on the Wii U eShop today for a limited time, enabling augmented reality Google Street View. Grab it now, because it seems unlikely you'd want to pay for it.
Meanwhile on 3DS eShop: video games! The NES version of arcade classic Dig Dug is available, as is a demo for chibi action game Naruto Powerful Shippuden. Bit.Trip Saga is also discounted. If you lack even one of the Bit.Trip games, this is a great way to get them all in a portable format.
