You could frame the regulation in a variety of ways:

1. Require a clear labeling of sunset date.

Or

2. Require an independent trust created from a portion of the initial payment to fund ongoing operation.

Or

3. Ban fixed payments for things with ongoing known operating costs.

Or

4. Provide local mechanisms to continue to run the game.

The original sin is a fixed price for an ongoing expense as a business model.
