In theory almost any Android device with video-out can be hooked up to a controller to play games, but only a few products have labeled themselves as full-blown consoles. In this article I’ll focus on the four most popular and well supported options; Gamestick, Ouya, M.O.J.O and Shield.
The more affordable end of the market is represented by Gamestick and Ouya, which sell for $79.99 and $99.99, respectively. Both are small, both use a custom storefront instead of Google Play, and both use older ARM processors to keep the price down.
On the other end of the spectrum is M.O.J.O and Shield, which sell for $249.99. These systems use the relatively new Nvidia Tegra 4 processor. The M.O.J.O. sells itself as an all-in-one media hub, while the Shield is a handheld and has the ability to stream a limited library of PC games.
