Where Is The Metered Pay Model For Online Games?

bturnip writes "I just cancelled my account with the game A Tale in the Desert. I really liked the game- it had a fresh interesting approach, a Linux client, a non-linear style of game play, and was just fun to play. The graphics were pretty good, the sheer amount of stuff to see and do was impressive, and the online community was extremely helpful and friendly. My problem? I didn't play often enough to justify paying $13.95 each and every month. Is isn't that the price is outrageous, I'm not having any problems paying the bills, I just didn't play enough to make it worth my while. Where is the metered pay model for the casual gamer? If a certain game has a monthly fee of $15, and the average player plays 40 hours a month, a metered model might offer 40 metered hours for $25. Hours could be set to expire after a set time, say 4-6 months. Some months I might pay more than a monthly subscriber, some months less. This is a win/win situation. I can have more fun playing my character at my own pace without feeling I need to play more often to justify the montly cost. The game gets money that it would not get otherwise. If I end up playing often, maybe I end up as a monthly subscriber. The downside I can see for game makers is the overhead of running two billing models, extra work in tracking hours spent, etc. What are the other downsides? Is the potential market for this type of billing not worth the effort?" Along these lines, I think that Planetside would have been a huge success if it had launched with a different subscription model.
