Lately I’ve been aggressively telling everyone I know to do more visualization of the systems they’re building, and thinking about what that might mean for the procedural text experiments I’ve been up to.
If you’ve played with The Mary Jane of Tomorrow, you’ve probably noticed that some of the poems it generates show a lot more variation and richness than others. That’s easy to observe, but can we quantify it? Can we draw observations about what level of complexity is the most satisfying, and identify portions of the game where more or less complexity would improve the experience? If we’re procedural text artists, how do we decide where to direct our attention?
One of the fun/horrifying things about this particular medium is that it pretty much never feels like you’re done: it would always be possible to add more corpora and more variant templates. Both Mary Jane and Annals of the Parrigues came to an end because I needed to move on to other work, not because I couldn’t think of anything further to add. But one thing I might want from a procgen text tool is help discerning where the biggest blank spots are currently.
The first step towards visualization is of course figuring out what aspects of the system you might want to look at, and in fact I often find “how would I draw a picture of this?” to be a good way of making myself think about the salient qualities of a particular system. Here are the things I decided I wanted to know about the text in Mary Jane:
Size of component phrases: how long is the smallest atom of text in a given composition? When you see something in the text, was that produced by a human or is it the juxtaposition of several pieces selected algorithmically? This is very varied in Mary Jane, with some poems or conversation options picking entire sentences, and other selections being just a word or two long. (Parrigues goes even further and composites town names from constituent syllables, but Mary Jane isn’t going that far.)
Number of alternatives: if a phrase was picked from a list, how many other options were there? Number of options is going to determine how unique a particular element is in your experience of the text.
Salience of selected phrase: why did we pick this piece? How many pieces of information about the world model did it have to match in order to be selected? (And to combine those two points, if we picked a highly salient phrase, how many other options were there of equal salience?)

For IF Comp 2015, I offered as a prize to contribute a piece set in the same universe as the author’s game. Steph Cherrywell chose this prize for
