The Game Portal is a free browser-based service that allows streaming of a selection of demos, as well as a limited number of full games for rent -- for a per-game fee, without the monthly charge. The selection of games is limited not just in number, but also "subject to available OnLive service capacity and whatever usage limits are associated with each given demo."
The Portal will work with the OnLive set top box, in addition to the browser plug-in. It is expected to roll out sometime in 2010, after the June 17 launch of the main service.
