You thought we were done talking about OnLive at GDC 2010, didn't you? Well we did too until we learned about the streaming PC game service's other plan to introduce itself to gamers. Earlier this week the company announced a June 17 launch date for their main OnLive service which will cost $14.95 a month with rentals and purchasing of games representing an added fee on top.

Now OnLive has announced plans to launch OnLive Game Portal. Unlike the monthly main service, OnLive Game Portal will be free to sign into. It will offer free game demos and a select amount of full games to rent. There seems to be a small caveat; according to OnLive, the free demos are " subject to available OnLive service capacity and whatever usage limits are associated with each given demo".

OnLive Game Portal is basically OnLive's version of "try before you buy". The OnLive Game Portal will launch sometime after OnLive's official launch.
