The Ouya, which still is in concept design, has already attracted its first exclusive game.
Robotaki has come out saying they will be producing a prequel to the game Human Element exclusively for the Ouya console. The president of Robotaki is best known for being one of the lead developers for the Call of Duty series while at Infinity Games.
This news means developers are already interested in the Android-based console. This bodes well for the future of the open source console, and is a bit of a threat to the next generation consoles being developed by Sony and Microsoft.
