OnLive's flat $10-per-month gaming package, Playback, was launched at the end of December, and was supposed to herald the official launch on January 15th. Unfortunately for the company, it doesn't look like that date is going to be met. However, due to the set-back, the company has rewarded its users the usage of Playback through the rest of January, completely free-of-charge.
The service, which offers unlimited access to OnLive's back-catalog of videogames, was supposed to see a full launch starting tomorrow (as of the time of this writing), but for unknown reasons it's been set back to an unknown date. The result is that OnLive is ready to set the beta onto all of OnLive's users, allowing them to access the catalog free-of-charge.
Playback was only originally available for OnLive users on the MicroConsole, but now the beta will be open to everyone that uses the service. On any platform that OnLive is accessible. As of right now, the catalog has only about 12 titles available to play, but OnLive says that the content will expand to about 40 titles once it leaves the beta status.
