some further info from the website:

Please choose the service level that best suits your situation. If you choose the Apprentice service, you're ready to check out. If you choose the Standard service or Patron service, you must also choose at least one game system to unlock. Additional content options can also be added for the game system(s) you select.

Here are a few important notes that may answer immediate questions:

Game systems and additional content are one-time purchases that are forever unlocked to your account. Only the service plan incurs a recurring charge, regardless of how much content you've unlocked.

You can add new game systems and/or rules supplements to your account at any time.

You can adjust your service plan over time, upwards or downwards, subject to certain limitations.

If your service should lapse, you still retain the ability to view what you've created (characters, campaigns, etc.).
