Hourly game cards (Score 1)

Any plans to release hourly game cards? Currently only bimonthly (60-day) cards are available, which waste away if not used after activation. For example, if I activate a card on July 1st, it expires on August 29th no matter how many hours a day I play. I (as well as many other users) would like to be able to purchase a game card for x number of hours and play it out over some period of time.
