I've tried playing interactive fiction games with it and it's not bad, but not too great either. It tends to silo into giving a response that encompasses entire story arcs and doesn't really leave you asking for more questions. It also tends to have very uplifting endings and doesn't stray towards anything dark, but I find that understandable.

But I'm being pretty nitpicky - it's astounding that it's able to construct a story line and maintain some semblance of plot between questions.
