- When you create an account, you hook it up to a credit card (same as now).
You make an initial deposit of $30 to your game account.
As you play, the game deducts hourly fees from this account (according to a sliding scale).
When the account goes below a certain threshold (say, $5), it bills another $30 to your credit card.
The game e-mails you a statement every month as an FYI (same as now).
If you don't play for several months, no money is deducted and your account remains active.
If you cancel your account, the balance is credited to your card.
