Questions to ask about your generator

I recently ran across this list of questions I came up with during my Roguelike Celebration talk a couple years ago, and I thought that it stands up pretty well on its own.

Individual: What effect does a single artifact have? What are the differences between artifacts? What makes this artifact stand out?

Gestalt: What is the overall impression of the generative space? What is the effect of the group of artifacts?

Repetition: What are the similarities between artifacts? What does the player learn about the generator from their commonalities?

Structure: What does this artifact tell us about the generative space? What processes can we discern? What can we predict about the next artifact we see?

Surface: What direct impact does this artifact have on our experience? What details do we pay attention to? 

Multiplicity: How much variance can we perceive across the generative space?

Cohesion: Do the artifacts feel like they belong? Do they fit in with the other artifacts? Can we perceive them as part of a cohesive system?

Style: How well do the artifacts fit their context? Can the generator adjust to match the current needs?

Are there other questions that you ask about your generators?
