From a 2017 comment:
Usual critiques of story generators tend to be some variant of "Yes, you can produce short evocative text snippets, but without structure, you can't scale your generator upwards". It seems approaches that require planning and outlines (story compilers, simulations, etc.) are an inverse of that, providing the structure to scale upwards, but are unable to generate the short evocative text snippets on their own.
This may not actually be a problem to worry about though - a human probably need to be in the loop somewhere (at least, if the story is to be enjoyable or useful to other humans).
>But if it does become an issue, maybe we need to have two generators -- use a Markov chain or RNNs to generate short evocative paragraphs for individual topics, and then a large-scale planner to pick paragraphs from those individual topics.
