This is awesome, but I don't get the repeated use of the term "one-shot". There were many human-driven requests and iterations, and this is illustrated in the blog post.

This really was more like a normal person had access to a game developer team (with artists and musicians) and had a custom game built based on interviews and playtesting.

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.
