The online gaming service is now free after many customers were disappointed with what their $15 got them and that was just access to the gaming community and free demos.
Full games, which cost anywhere from $10 to $50, were additional on top of the monthly "access" charge. I can see why people were upset.
Evidentially this was OnLive's plan all along but it couldn't be announced until they had built a large base of regular users.
They wanted to find out if the service could be supported without monthly subscriptions.
