Ouya is off to a good start. Following a very successful Kickstarter campaign, the open-source game console finally launched to the public this morning, and just hours into the day it has already sold out on Amazon. Of course, it’s hard to gauge how well it’s selling without knowing how many were available in the first place. For what it’s worth the company says it has shipped ’tens of thousands’ units to early backers.

The $99 console features an Nvidia Tegra 3 processor, 1GB of RAM, and 8GB of internal storage -- expandable via USB. It ships with one wireless controller, over 170 free-to-try games, as well as streaming services such as Twitch.tv, TuneIn, XBMC, iHeartRadio and Plex. Extra controllers will run you $49.99 each.

Also included is the Make Channel, which enables developers to build and test games right from the hardware. The company says more than 10,000 developers worldwide have signed on to create content for the Ouya, so you can expect new titles “every day, every week.” Whether these titles will be able to challenge AAA releases on the upcoming generation of consoles from Sony and Microsoft remains to be seen. But Ouya isn’t passing on the opportunity to throw a few jabs at its opponents saying they are “not the same old games by the same old folks adding +1 to the version number and slapping on a price tag of $60 or more.”

Despite the initial enthusiasm over the affordable console not everything has gone without a hitch. Besides the delay from its original launch date on June 4, many early backers have yet to receive their units, despite promises that they would have them before the console hit retail stores.

Ouya CEO Julie Uhrman says they are working over time to resolve this issue, explaining that the vast majority of affected users are international backers, and it just takes more time to ship to some countries.

Interested buyers can also shop for the Ouya at Best Buy, GameStop and Target.
