The initial range of pricing options includes rentals that last three or five days and an unlimited pass that provides access until at least 17th June 2013 - presumably the length of the current licensing agreements. Buying a game through OnLive entitles you to access that game for the length of the agreed licence, providing you keep up your OnLive subscription. If you allow that to lapse, you can't access the games again until you rejoin. The organisers are currently offering free subscriptions for the first year then reduced rates during the second for "founding members".
