I disagree. Fable didn't make any mistakes and created a completed game with zero guidance, so it's a one-shot. If additional requests come up afterwards, it doesn't detract from the initial execution.

That is my definition of one shot as well. I consider the app I made "one shotted". But by that, I mean each feature is a single shot. The app is a collection of over a hundred of those shots..and counting.
