There is no dearth of good, albeit mostly casual, games on the App Store. Controlling them, however, is another story. If your gaming console of preference happens to be an iPad, you might want to take a good look at this, the Wikipad Gamevice.
The Gamevice is simple: strap it on your iPad, and, et voila, enjoy your new portable gaming machine. Controls are standard console style, with dual sticks, D-pad, four action buttons and four shoulder buttons. Wikipad will sell the Gamevice in different variants for the iPad mini and iPad Air, and each model of Gamevice will fit different generations of each iPad: the Air-compatible Gamevice will work with iPad Air 1 and iPad Air 2, and all three generations of iPad mini will play nicely with that model. Pre-Air 9.7-in iPads (late 2012 and earlier), aren’t supported.
There will also be 4G LTE versions of the Gamevice that create Wi-Fi hotspots for your iPad. Wikipad hasn’t finalized the details of these models, but it says the data will cost around US$10 a month, and will give you respectable amounts of monthly data (perhaps in the 5 GB range).
The standard version has an 800 mAh battery, which the company says will have it lasting four full iPad charge cycles. The LTE versions will have 1,600 mAh batteries to compensate for the extra juice that the Wi-Fi hotspot will gobble up.
